How long is a rabbit's gestation period?

The average rabbit gestation period is 31 days, with a normal range of 28–34 days. Kits born before day 28 are usually premature and rarely survive. Most kindlings occur around day 30–32.

How do I know if my rabbit is pregnant?

The most reliable method is gentle abdominal palpation around day 14 — an experienced handler can feel marble-sized bumps in the uterine horns. Changes in behavior (increased nesting, more defensive) may also indicate pregnancy. A veterinarian can confirm pregnancy via ultrasound from day 10–14.

What should I put in the nest box for a rabbit?

Line the nest box with clean hay or straw, about 3–4 inches deep. The doe will add her own pulled fur on top. Place the box in the hutch on day 27–28 — too early and the doe may use it as a litter box; too late and she may kindle on the hutch floor.

How can I calculate my rabbit's kindling date?

Use our rabbit gestation calculator — enter the breeding date and get the expected kindling date (day 31), earliest possible date (day 28), and latest expected date (day 34). The calculator also shows key milestones including nest box placement timing.

Rabbit Gestation Period: Complete Guide

The rabbit gestation period averages 31 days — one of the shortest pregnancies among common domestic animals. Whether you're a commercial rabbit producer or a backyard breeder, understanding the rabbit pregnancy timeline helps you prepare the nest box at the right time, recognize the signs of imminent kindling, and give the doe and her kits the best start.

How Long Are Rabbits Pregnant?

Rabbits are pregnant for an average of 31 days, with a normal range of 28–34 days. This is considerably shorter than most farm animals — goats gestate for 150 days, sheep for 147 days, and cattle for 283 days. The short gestation is part of the rabbit's reproductive strategy: compensate for high predation by reproducing rapidly with large litters.

Rabbit gestation length varies slightly by breed. Smaller breeds like Mini Rex tend to kindle around day 30, while larger breeds like Flemish Giant may carry to day 32. First-time does occasionally kindle as early as day 28 or as late as day 34. A kindling before day 28 produces premature kits that typically do not survive.

Rabbit Gestation by Breed

Breed	Avg. Gestation (Days)	Typical Litter Size
New Zealand White	31	8–12
Californian	31	6–10
Flemish Giant	32	7–12
Rex	31	6–10
Holland Lop	31	3–7
Mini Rex	30	4–8

Signs a Rabbit Is About to Kindle

The most reliable sign is fur pulling — the doe pulls fur from her dewlap and flanks to line the nest box. This typically begins 1–3 days before kindling, though some does pull fur right before or even during birth. Other signs include:

Increased restlessness and territorial behavior
Loss of appetite 12–24 hours before kindling
The doe spending more time in or near the nest box
Visible belly movement as kits shift position

Most does kindle in the early morning hours and the entire process usually takes 15–30 minutes. Does rarely need assistance. Avoid disturbing the doe during active kindling.

The Nest Box: Timing and Setup

The nest box is the most important preparation for kindling. Place it in the hutch on day 27 or 28 of pregnancy. Placing it earlier may lead the doe to use it as a litter box; placing it too late risks the doe kindling on the hutch floor, where kits can fall through wire and become chilled.

The box should be large enough for the doe to turn around inside but not so large that the kits scatter. Fill it with 3–4 inches of clean straw or hay. The doe will pull fur from her body to insulate the nest — a normal and healthy behavior.

Caring for Kits After Kindling

Check the nest box the morning after the expected kindling date. Remove any stillborn kits immediately. Ensure the surviving kits feel warm (room temperature or slightly warmer) and their bellies look full and rounded after nursing. Does nurse only once or twice daily, usually at night — the absence of the doe from the nest box during the day is normal.

If kits feel cold and lethargic, warm them gently in your hands before returning them to the nest. Rabbit milk replacer is available if the doe refuses to nurse, though hand-raising kits from birth is challenging.

How to Calculate Your Rabbit's Due Date

Add 31 days to the breeding date for the expected kindling date. Our rabbit gestation calculator does this instantly and shows the full 28–34 day range so you know when to place the nest box and when to expect kindling. For comparison with other animals, see our full gestation periods chart.
