Rabbit Cage Setup for Breeding: Doe and Litter Housing

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-14

Key Takeaways

Cage dimensions are critical for doe and litter health: Minimum cage sizes vary by breed class, with medium breeds requiring at least 30x36 inches and jumbo breeds needing 36x48 inches, to prevent crushing kits and allow adequate movement.
Nest box design and placement are paramount for kit survival: A nest box of appropriate size (e.g., 18x10x10 inches for medium breeds) with a low opening (approx. 6 inches high) should be installed on day 27 of gestation in a quiet, back corner to prevent chilling and crushing.
Flooring and sanitation are key to preventing disease: 14 gauge welded wire with 1/2 by 1 inch mesh is recommended for the main floor to allow waste to pass through, while nest boxes require frequent cleaning (daily to every two days in the first week) to remove soiled bedding and prevent enteritis.
Environmental control is essential for successful kindling: Maintaining a temperature range of 50-70°F, ensuring adequate ventilation to control humidity (below 70%), and providing 14-16 hours of light daily are crucial for doe health and breeding performance.
Monitoring kits for signs of adequate nursing and health is vital: A full, round belly indicates successful nursing; wrinkled or flat bellies suggest insufficient milk intake or competition, necessitating checks for mastitis in the doe or potential kit mortality.
Weaning protocols are breed-dependent and require separate housing: Kits are typically weaned at 4-6 weeks, moving to a grow-out pen with at least 1.5 square feet per kit to prevent stress and disease transmission.

Setting up a breeding cage system that supports both the doe and her litter through kindling and weaning is one of the most important decisions you will make as a rabbit breeder. This guide covers the full process of designing, building, placing, and maintaining doe cages with nest boxes, from the weeks before breeding through the day the kits are weaned. It is written for small to mid-scale rabbit producers, homesteaders, and 4-H or FFA members who need practical, tested housing solutions that keep rabbits healthy and reduce kit losses.

Why Breeding Cage Design Matters

The cage you use for a breeding doe is not the same as a cage for a single adult rabbit. A doe cage must serve three distinct purposes over a single reproductive cycle. It must provide a secure place for mating, a safe and quiet area for kindling, and a protected space where the doe can nurse her kits without crushing them or being disturbed by other rabbits.

Many preventable kit losses trace back to housing failures. Kits die from chilling when the nest box is drafty or poorly positioned. They die from crushing when the doe cannot enter and exit the nest box easily. They die from diarrhea and enteritis when the nest box is not cleaned properly or when the cage floor allows droppings to accumulate where kits are nursing. Does that are stressed by overcrowding, poor ventilation, or constant disturbance may refuse to nurse, scatter their kits, or even kill them.

A properly designed breeding cage reduces these risks before they become problems. The cage itself should be roomy enough for the doe to move freely but not so large that she cannot keep the nest area warm. The nest box should be removable for cleaning and inspection. The floor should protect the doe's feet while still allowing waste to fall through. The placement of the cage within the rabbitry should give the doe visual privacy during kindling and nursing while still allowing you to check on her easily.

Understanding the Doe's Reproductive Timeline

Before you build or buy cages, you need to understand the timing of the breeding cycle. This timeline drives every housing decision you will make.

A doe reaches sexual maturity at 4 to 6 months for small breeds, 5 to 7 months for medium breeds, and 6 to 9 months for giant breeds. You should not breed a doe on her first heat cycle. Wait until she is at least 80 percent of her adult weight. Breeding too young produces small litters, difficult kindling, and poor mothering behavior.

Once bred, the doe carries her kits for 28 to 34 days, with 31 days being the average for most breeds. You should place the nest box in her cage on day 27 of gestation. This gives her two to four days to investigate the box, arrange nesting material, and pull fur. Does that receive the nest box too early may soil it or use it as a toilet. Does that receive it too late may kindle on the wire floor, which almost always results in dead kits.

The doe will typically pull fur from her belly and chest in the 24 to 48 hours before kindling. This is not just maternal instinct. Pulling fur exposes her nipples so kits can nurse more easily, and the fur lines the nest to keep kits warm. Some does pull fur a week before kindling. Others wait until the actual birth. Both patterns are normal.

Kindling itself usually takes 10 to 30 minutes for a normal litter. The doe will deliver each kit in its own amniotic sac, clean it, and move it into the nest. She will eat the placenta. Within an hour of finishing, she should be in the nest box nursing her kits. Kits nurse once or twice per day, usually at dawn and dusk, for only about five minutes per session.

Kits open their eyes at 10 to 14 days. They start moving out of the nest box at 14 to 18 days. By 21 days they are fully mobile and eating solid food alongside their mother's milk. Most producers wean kits at 4 to 6 weeks, depending on breed size and the doe's condition.

Cage Size Requirements by Breed Class

Cage size is the single most common mistake in breeding rabbit housing. A cage that is too small stresses the doe, increases the risk of foot problems, and makes it harder for her to nurse without stepping on her kits. A cage that is too large wastes space and can make it harder for the doe to keep the nest warm in cold weather.

Use these minimum dimensions for a single doe with a litter. These are floor space recommendations, not including the nest box, which is discussed separately.

For small breeds like Netherland Dwarfs and Polish rabbits, provide a cage at least 24 inches wide by 24 inches deep and 16 inches high. A doe of this size will produce litters of 3 to 5 kits. The small nest box will take up a significant portion of the floor, so do not go smaller than these dimensions.

For medium breeds like New Zealands, Californians, and Rex rabbits, provide a cage at least 30 inches wide by 36 inches deep and 18 inches high. This is the most common size sold commercially and works well for the majority of commercial and homestead operations. These does produce 8 to 12 kits per litter, and the extra floor space gives the doe room to move around the nest box without stepping on kits that have started venturing out.

For large breeds like Flemish Giants and Checkered Giants, provide a cage at least 36 inches wide by 36 inches deep and 20 inches high. Some producers prefer 36 by 48 inches for the largest does. These breeds produce 8 to 14 kits, and the doe herself may weigh 12 to 15 pounds. She needs room to turn around, stretch out, and enter the nest box comfortably.

For jumbo breeds like the Giant Chinchilla or the larger strains of Flemish Giant, go with 36 by 48 inches minimum. Do not attempt to keep a jumbo doe in a standard 30 by 36 inch cage. Her weight and size will make movement difficult, and she may have trouble positioning herself to nurse without crushing kits.

Height matters more than many new breeders realize. The cage should be tall enough that the doe can sit upright on her haunches without her ears touching the top. For lop-eared breeds with heavy ear carriage, 18 inches is usually sufficient. For breeds with upright ears like the Belgian Hare or the English Spot, provide 20 to 24 inches of height.

Choosing Cage Materials

The two main options for breeding cages are all-wire cages and cages with solid floors or solid resting areas. Each has advantages and disadvantages that matter specifically for breeding does and their litters.

All-wire cages with 14 gauge galvanized wire are the industry standard for commercial rabbit production. The wire floor allows urine and droppings to fall through into a collection tray or onto the floor below. This keeps the cage cleaner, reduces ammonia buildup, and makes sanitation much easier. The main floor should use 1/2 by 1 inch mesh. This size allows droppings to pass through while providing enough support for the doe's feet. Smaller mesh like 1/2 by 1/2 inch is harder on the doe's feet and does not let droppings fall through as easily. Larger mesh like 1 by 1 inch can trap feet and cause broken toes or legs.

The walls of an all-wire cage can use 1 by 2 inch mesh for larger breeds or 1 by 1 inch for smaller breeds. The larger mesh on the sides improves airflow, which is important in hot weather. However, if you have predators in your area like raccoons or dogs, use 1/2 by 1 inch mesh on all sides to prevent them from reaching through and grabbing kits.

Solid floor cages, usually made of plastic or galvanized metal with a solid pan, are easier on the doe's feet but require much more frequent cleaning. A solid floor with a nest box can become soiled quickly, especially in the first week after kindling when the doe is producing large amounts of milk and the kits are urinating frequently in the nest. If you use solid floors, plan to clean the cage daily and the nest box every one to two days.

Many producers use a hybrid approach. They keep the main cage floor as wire but install a solid resting board or mat in one corner. This gives the doe a place to rest her feet while still keeping most of the cage self-cleaning. If you use a resting board, place it away from the nest box so the doe does not rest directly on top of her kits. The board should be removable for cleaning and should be made of a material that does not absorb urine, such as plastic or sealed wood.

For the nest box itself, you have three main material options. Wood nest boxes are traditional and provide excellent insulation. They are also absorbent, which means they hold moisture and need to be replaced or thoroughly cleaned between litters. Use untreated pine or fir, never pressure-treated wood, which contains chemicals toxic to rabbits. Line the bottom with a layer of newspaper and straw to make cleaning easier.

Plastic nest boxes are easier to sanitize than wood. They do not absorb urine and can be washed with hot soapy water and a mild disinfectant between uses. The downside is that plastic does not breathe, so condensation can build up inside during cold weather. Some plastic nest boxes have perforated bottoms or sides to improve airflow. These work well in most climates.

Metal nest boxes, usually galvanized steel, are the most durable and the easiest to sanitize. They are also the coldest. In winter, a metal nest box without adequate bedding will chill the kits. If you use metal, fill the box generously with straw and provide extra nesting material so the doe can build a proper nest. Some producers line metal boxes with cardboard or wood shavings to add insulation.

The Nest Box: Design and Placement

The nest box is the most important piece of equipment in your breeding cage setup. Its design determines whether the doe can enter and leave easily, whether she can arrange her nest properly, and whether the kits stay warm and dry.

For medium breeds, an acceptable nest box measures 18 inches long, 10 inches wide, and 10 inches high. The front opening should be about 6 inches tall and 6 inches wide. This opening must be low enough that a doe of your breed can step over it easily but high enough that kits cannot crawl out before they are ready. A lip or threshold of 2 to 3 inches at the bottom of the opening helps keep bedding inside the box.

For small breeds, reduce the dimensions to 14 inches long, 8 inches wide, and 8 inches high with a 5 inch opening. For large and giant breeds, increase to 24 inches long, 14 inches wide, and 12 inches high with an 8 inch opening. A nest box that is too small will not hold the full litter once kits start moving around. A nest box that is too large is harder for the doe to keep warm and may result in kits scattering away from the warmth of the pile.

The box should have solid sides to block drafts. A fully enclosed box with a top is best for outdoor rabbitries. The top should be hinged or removable so you can check on the kits without disturbing the doe. If the box has no top, the doe can jump out over the side, which is fine, but you will need to reach in from above to check kits, which can startle her.

Place the nest box in the back corner of the cage, away from the door and away from the water bottle. This gives the doe privacy and reduces the chance that kits will be exposed to drafts when you open the cage door. The box should be flush against the back wall and one side wall of the cage. This prevents kits from slipping behind the box and also makes the box feel more secure to the doe.

You will need a way to secure the nest box so the doe cannot tip it over or drag it around the cage. Many commercial cages come with a built-in nest box holder or a clip system. If your cage does not have this, use wire ties or S-hooks to anchor the box to the cage floor or wall. The box must be removable for cleaning, so use a system that allows quick release.

Install the nest box on day 27 of gestation. If you are not certain of the breeding date, install it when you first notice the doe pulling fur or when her belly looks noticeably enlarged and she begins to spend more time resting. It is better to install the box a day early than a day late.

Nesting Material and Bedding

The nesting material you provide serves two purposes. It gives the doe material to build a nest, and it provides insulation and moisture control for the kits. The doe will combine the material you provide with fur she pulls from her own body.

Use clean, dust-free straw, hay, or a combination of both. Wheat straw is the most common choice because it is inexpensive, does not mold easily, and provides good structure for the nest. Grass hay like timothy or orchard grass is softer and more absorbent but breaks down faster. Do not use alfalfa hay for nesting material. It is too coarse and can irritate the kits' skin. Do not use cedar shavings or any aromatic wood shavings. The oils in cedar are toxic to rabbits and can cause respiratory problems and liver damage.

Fill the nest box about two-thirds full with nesting material. Fluff it up so the doe can arrange it to her liking. Do not pack it down. The doe will rearrange the material and create a depression in the center where the kits will lie. Some does will use almost all the material you provide. Others will push most of it out of the box and rely on their own fur. If you see the doe pushing material out, that is normal behavior. She is making the nest to her own specifications.

In cold weather, provide extra nesting material. The kits are born hairless and cannot regulate their own body temperature for the first week. They rely entirely on the nest and their littermates for warmth. A good nest should be deep enough that the kits are completely hidden from view when you look down into the box.

In hot weather, reduce the amount of nesting material. Kits can overheat in a heavily lined nest box when temperatures exceed 85 degrees Fahrenheit. Provide just enough material for the doe to build a shallow nest, and make sure the nest box has adequate ventilation. Some producers remove the top from the nest box during heat waves to improve airflow.

Check the nest box daily and remove any soiled bedding immediately. Urine-soaked bedding chills kits and promotes bacterial growth. In the first week, you may need to replace bedding every one to two days. After the kits start moving around and leaving the box to eat solid food, the bedding will stay cleaner because most waste falls through the wire floor outside the box.

Cage Placement and Environmental Control

Where you place your breeding cages within the rabbitry is almost as important as the cages themselves. Does that are about to kindle need quiet, privacy, and protection from temperature extremes.

Place breeding cages in the most protected area of your rabbitry. This should be away from doors, windows, and vents that create drafts. A doe that is chilled during kindling may abandon her kits or be too sluggish to clean them properly. Kits that are chilled for even a few minutes after birth can die.

Temperature management is critical for breeding rabbits. The ideal temperature range for a rabbitry is 50 to 70 degrees Fahrenheit. Does can tolerate temperatures down to 40 degrees if they have a well-lined nest box, but kindling in extreme cold increases kit mortality. Above 85 degrees, does become heat stressed, eat less, produce less milk, and may abandon their litters. In hot climates, provide fans for airflow, freeze water bottles for the does to lean against, and consider moving breeding cages to the coolest part of the building during summer.

Humidity also matters. High humidity above 70 percent promotes bacterial growth in the nest box and increases the risk of respiratory disease. Ensure your rabbitry has adequate ventilation to remove moisture from urine and respiration. In winter, do not seal the building completely. Some airflow is necessary even in cold weather to prevent ammonia buildup.

Lighting affects breeding behavior. Rabbits are seasonal breeders, with reduced fertility and libido during short winter days. Provide 14 to 16 hours of light per day for breeding stock to maintain year-round production. A simple timer-controlled light works well. The light should be bright enough for you to inspect the rabbits but not so bright that it stresses them. Avoid direct sunlight on the cages, which can overheat the nest box.

Position cages so the doe can see other rabbits but has some visual privacy during kindling. Total isolation can be stressful for a social species. Partial visual barriers, such as a solid panel on one side of the cage or a curtain over the front during kindling, give the doe privacy without removing her from the social environment of the rabbitry.

Step-by-Step Setup for the Breeding Cycle

Follow this sequence for each breeding cycle to ensure the doe has the right housing at the right time.

Step 1: Pre-breeding preparation, days 14 to 21 before breeding. Clean and disinfect the doe cage thoroughly. Remove any residual hair, manure, or feed from the previous occupant. Check all wire for sharp edges, broken welds, or gaps where kits could escape. Repair any damage before breeding. The doe should be in the cage at least two weeks before breeding so she can establish the cage as her territory.

Step 2: Breeding, day 0. Take the doe to the buck's cage for breeding, never the reverse. The doe is territorial and may attack a buck placed in her cage. After breeding, return the doe to her own cage. The cage should be clean and free of any debris that could injure the doe during mating.

Step 3: Days 1 to 14 of gestation. Continue normal feeding and care. The doe does not need any special housing during this period. Keep her in her regular cage with normal cleaning schedules. Handle her gently and minimize stress. A startled doe can abort her pregnancy.

Step 4: Day 14, palpation check. If you are experienced, you can palpate the doe to confirm pregnancy at day 14. If you are not experienced, skip this step and simply wait. Do not handle the doe roughly during this period.

Step 5: Days 15 to 26 of gestation. The doe's appetite will increase significantly. Ensure she has plenty of feed and fresh water. The cage should be kept clean to reduce the risk of infection. Some producers increase the amount of hay or fiber in the diet during this period to support the developing kits.

Step 6: Day 27, install the nest box. Place the clean, disinfected nest box in the back corner of the cage. Fill it two-thirds full with nesting material. Secure the box so the doe cannot tip it. Expect the doe to investigate the box, rearrange the material, and possibly pull fur. Do not disturb her during this period except for routine feeding and watering.

Step 7: Days 28 to 31, watch for kindling. Check the doe twice daily, morning and evening. Signs that kindling is imminent include restlessness, excessive fur pulling, and nesting behavior. The doe may become aggressive or defensive of her nest. Do not reach into the cage without warning her first. When you open the cage, speak softly and move slowly.

Step 8: Day of kindling, day 31 on average. After the doe has kindled, leave her alone for at least an hour to allow her to clean the kits and begin nursing. After one hour, check the nest box. Remove any dead kits, placentas, or wet bedding. Count the live kits and note their condition. Do not handle the kits more than necessary. If the doe seems agitated, wait a few more hours before checking again.

Step 9: Days 1 to 7 after kindling. Check the kits twice daily. Each kit should have a full, round belly after nursing. A kit with a wrinkled, empty belly is not getting milk. Check for signs of chilling, such as bluish skin or lethargy. Remove any dead kits promptly. Clean the nest box as needed, removing soiled bedding and replacing it with fresh material.

Step 10: Days 8 to 14 after kindling. Kits will begin to grow fur and open their eyes. Reduce nest checks to once daily. The kits will start to move around the nest box. Continue cleaning as needed. The doe will spend more time away from the nest, which is normal.

Step 11: Days 15 to 21 after kindling. Kits will start leaving the nest box to explore the cage and eat solid food. Provide a low-sided dish of starter pellets and a water bottle positioned low enough for kits to reach. The kits will continue to nurse but increasingly rely on solid food. Keep the cage clean, as kits are not yet coordinated enough to use the wire floor effectively.

Step 12: Days 21 to 28 after kindling. The kits are fully mobile and eating solid food. The nest box can be removed at this point if the kits are no longer using it. Some producers remove the box at day 18, others leave it until weaning. If you remove the box, provide a small hide box or shelter in the cage so the kits feel secure.

Step 13: Weaning, days 28 to 42. Wean kits based on breed size and the doe's condition. Small breeds can be weaned at 4 weeks. Medium breeds at 5 to 6 weeks. Large breeds at 6 to 8 weeks. Move the kits to a grow-out cage separate from the doe. The doe should be returned to her regular cage, dried off, and given a few days to recover before being rebred if you are following a continuous breeding schedule.

Common Mistakes in Breeding Cage Setup

New rabbit breeders tend to repeat the same housing mistakes. Recognizing these problems before they cost you a litter will make your operation more successful.

Mistake 1: Using a cage that is too small. The most common error is trying to save space by keeping a doe with a litter in a cage sized for a single rabbit. A cramped doe cannot position herself to nurse without crushing kits. She may also become aggressive from stress. If your doe cannot stretch out fully in her cage with the nest box in place, the cage is too small.

Mistake 2: Installing the nest box too early or too late. A nest box installed too early becomes a toilet. A nest box installed too late means the doe kindles on the wire floor. Mark your calendar for day 27 of gestation and stick to that schedule. If you are unsure of the breeding date, install the box when the doe begins pulling fur or when she starts carrying hay in her mouth.

Mistake 3: Using the wrong mesh size on the floor. Floor mesh that is too large allows kits to fall through or trap their legs. Mesh that is too small does not allow droppings to fall through and causes foot problems in the doe. Use 1/2 by 1 inch mesh for the main floor and 1/2 by 1/2 inch mesh in the nest box area if you use a wire-bottomed box.

Mistake 4: Poor nest box design. A box that is too tall for the doe to enter easily, too shallow to contain the bedding, or too open to block drafts will lead to kit losses. The opening must be low enough for the doe to step over while she is heavily pregnant. The sides must be high enough to contain the nest and block drafts.

Mistake 5: Ignoring sanitation. A dirty nest box is a death sentence for kits. Urine-soaked bedding causes chilling, ammonia burns, and bacterial infections. Clean the nest box every one to two days in the first week. Disinfect the box between litters. Never reuse nesting material from a previous litter.

Mistake 6: Placing the nest box in the wrong location. A nest box near the cage door exposes kits to drafts and disturbance every time you open the cage. A nest box in the center of the cage leaves the doe no quiet corner. Place the box in the back corner, away from traffic.

Mistake 7: Not securing the nest box. A doe can tip a loose nest box, spilling her kits onto the wire floor. Kits that are not returned to the nest within minutes will chill and die. Always secure the box with clips, wire ties, or a built-in holder.

Mistake 8: Overcrowding the grow-out cage. Once kits are weaned and moving to grow-out cages, many breeders overcrowd them to save space. Overcrowded kits fight, spread disease, and fail to gain weight. Provide at least 1.5 square feet of floor space per kit for medium breeds, more for larger breeds.

Monitoring the Doe and Litter

Daily monitoring is the key to catching problems before they become fatal. Develop a routine that covers both the doe and the kits.

Check the doe's feed intake daily. A doe that is eating well is usually producing milk well. A doe that suddenly reduces her feed intake may be sick, stressed, or developing mastitis. Check her water bottle daily to ensure it is working and full. A lactating doe drinks twice as much water as a dry doe.

Check the doe's body condition weekly. She should maintain a healthy weight throughout lactation. A doe that loses too much weight while nursing will come out of the breeding cycle in poor condition and may not conceive on the next breeding. Increase feed as needed during lactation. Many producers feed a lactating doe free-choice pellets plus additional hay.

Check the kits for signs of adequate nursing. A well-fed kit has a round, full belly. A hungry kit has a wrinkled, flat belly and may be restless or crying. Kits that are not nursing may be too weak to compete with littermates, or the doe may not be producing enough milk. If you see consistently hungry kits, check the doe's nipples for signs of mastitis, which appears as red, swollen, or hard mammary tissue.

Check the nest for warmth and dryness. Kits that are chilled will be pale, lethargic, and piled tightly together. Kits that are overheated will be spread out and may be panting. The nest should feel warm and dry to the touch. If the bedding is wet, replace it immediately.

Count the kits daily for the first week. This is unpleasant but necessary. You need to know if kits are dying so you can identify the cause. A litter that is losing kits to chilling or crushing has a housing problem. A litter that is losing kits to diarrhea or infection has a sanitation problem. A litter that is losing kits with no obvious cause may have a disease problem that requires veterinary attention.

Weigh the kits at day 7 and day 21. A healthy kit should weigh about 100 grams at birth for medium breeds, 200 grams at day 7, and 400 to 500 grams at day 21. Significant deviations from these numbers indicate a problem with milk production, competition in the litter, or disease.

Record Keeping for Breeding and Housing

Good records let you identify which does produce well in which housing conditions. Without records, you are guessing.

For each doe, record her breed, age, and weight at first breeding. Record the date of each breeding and the buck used. Record the kindling date, litter size, number born alive, number weaned, and average kit weight at weaning. Record any health problems, including mastitis, kit deaths, or respiratory issues.

For housing, record which cage the doe was in for each litter, the nest box type, the bedding material used, and any changes you made to the setup. This information helps you identify patterns. If a particular cage consistently produces poor results, the cage itself may be the problem. If a particular doe produces well in one cage but poorly in another, the housing may be affecting her.

Record environmental conditions, including temperature, humidity, and ventilation status during each kindling and the first week after. This helps you understand how weather affects your kit survival rates. You may find that your nest boxes need more bedding in cold weather or that your rabbitry needs better ventilation in summer.

Use a simple spreadsheet or a paper notebook. The format matters less than consistency. Record something every day, even if it is just a checkmark that all rabbits are healthy and eating.

When to Call a Veterinarian or Extension Agent

Most breeding and kindling proceeds without veterinary intervention. You should know when to call for professional help.

Call a veterinarian immediately if a doe is in labor for more than 30 minutes without producing a kit. This may indicate a stuck kit, which is a life-threatening emergency. A doe that is straining, panting, and obviously distressed needs help. Do not wait to see if she resolves the problem on her own.

Call a veterinarian if you see signs of mastitis. Red, swollen, hot, or hard mammary tissue, especially with the doe refusing to nurse, requires treatment. Mastitis can progress to a systemic infection within 24 hours.

Call a veterinarian if you have a litter with multiple kits dying in the first week with no obvious cause. This may indicate a bacterial infection like pasteurellosis or a viral disease. Do not try to treat the kits yourself. Prompt diagnosis can save the rest of the litter and prevent spread to other rabbits.

Call a veterinarian if any kit shows signs of severe illness. Symptoms include diarrhea, bloating, discharge from the eyes or nose, or failure to grow despite adequate nursing. Young kits can deteriorate rapidly.

Call your extension agent if you have questions about cage design, ventilation, or environmental control. Extension agents have access to research-based recommendations for your specific climate and production system. They can also help you connect with local rabbit producer groups and veterinary resources.

Call your extension agent if you are planning to expand your operation and need guidance on facility design, waste management, or regulatory compliance. They can help you avoid costly mistakes.

Frequently Asked Questions

How big should the nest box be for my breed of rabbit?

Measure your doe from nose to base of tail. The nest box should be approximately two-thirds of her body length. For medium breeds like New Zealands, use an 18 by 10 by 10 inch box. For small breeds, use a 14 by 8 by 8 inch box. For large and giant breeds, use a 24 by 14 by 12 inch box. The opening should be tall enough for the doe to enter without scraping her back but low enough that kits cannot escape before they are mobile.

Should the nest box have a bottom or be open to the cage floor?

A nest box with a solid bottom is almost always better for breeding. The solid bottom holds bedding in place, provides insulation, and keeps kits from falling through the wire floor. If you use a wire-bottomed nest box, you must provide a solid insert or a thick layer of bedding to protect the kits. Most commercial producers use solid-bottom plastic or wood boxes.

How long should I leave the nest box in the cage after kindling?

Leave the nest box in the cage until the kits are 18 to 21 days old and fully mobile. By this age, kits are leaving the box on their own to eat solid food and explore the cage. Once they stop returning to the box to sleep, you can remove it. Removing the box too early forces kits onto the wire floor before they are coordinated enough to move safely.

Can I use the same cage for breeding, kindling, and grow-out?

You can use the same cage for breeding and kindling, but you should not keep weaned kits in the same cage where they were born without modifications. Once kits are weaned, they need a clean cage with no nest box and no residual scent of the doe. This reduces stress and disease transmission. Many producers use a separate grow-out cage or a partitioned area of a larger cage for weaned kits.

How often should I clean the nest box during the first week after kindling?

Check the nest box twice daily during the first week. Replace bedding whenever it becomes wet or soiled. This may be every day or every other day, depending on the litter size and the doe's habits. A doe that urinates in the nest box will require more frequent cleaning. Always remove dead kits immediately and replace the soiled bedding around the remaining kits.

What do I do if the doe refuses to use the nest box?

If the doe kindles on the wire floor instead of in the nest box, you must act quickly. Gather the kits gently and place them in the nest box with the nesting material. If the doe has not pulled fur, you can take fur from another doe or use a soft cotton ball to line the nest. If the doe continues to ignore the nest box after kindling, she may be a poor mother and should not be rebred.

How do I prevent the doe from crushing her kits?

Crushing is usually caused by a doe that cannot move easily in her cage or a nest box that is too small for her to position herself properly. Ensure the cage is large enough for the doe to move around the nest box. Make sure the nest box opening is low enough that she can step in and out without climbing over the side. Some producers add a small ledge or step in front of the nest box to help the doe enter smoothly.

What is the best flooring for a breeding cage?

The best flooring is 14 gauge welded wire with 1/2 by 1 inch mesh. This mesh size supports the doe's feet, allows droppings to fall through, and prevents kits from falling through. If you are concerned about foot health, add a solid resting board in the cage away from the nest box. Do not use 1 by 1 inch mesh on the floor, as this can trap feet and cause serious injury.
