Rabbit Gestation Calculator
Enter your doe's breeding date and her breed to get the estimated kindling date, the full kindling window, the current pregnancy day, days remaining, and a reminder for when to place the nest box. Gestation periods are tailored to each breed, from compact Dwarf and Dutch rabbits at around 30 days to larger Flemish Giants and French Lops that often carry to 32 days.
How to use this calculator
Select the breeding date from the calendar and choose the closest breed match. The calculator instantly returns the expected kindling date, the full kindling window (earliest to latest birth for that breed), the date to place the nest box, and - if the breeding date has already passed - the current pregnancy day and days remaining. The milestone schedule below shows every key date from implantation through kindling, formatted as a calendar timeline.
Rabbit gestation period: what to expect
Rabbits are induced ovulators: the doe releases eggs in response to mating rather than on a fixed cycle, so conception almost always occurs on the day of breeding. From that point the average gestation is 31 days, though the normal range spans 28 to 35 days depending on breed, litter size, and individual variation. Compact breeds (Dutch, Dwarf) tend toward the lower end at about 29-31 days, while giant breeds (Flemish Giant, French Lop) often carry to 32 days. Litters born before day 28 are rarely viable; does that have not kindled by day 35 should be examined by a veterinarian, as retained kits can be life-threatening.
Key pregnancy milestones and care tips
During the first week after breeding the fertilized eggs travel to the uterus and implant around day 7. From day 14 to day 21 a skilled handler can gently palpate the abdomen and feel grape-sized embryos - the best non-invasive way to confirm pregnancy. Around day 22 the doe may start rearranging her bedding or showing nesting behavior. Place a clean nest box filled with hay or straw no later than day 27: does often build the nest right away and pull fur from their dewlap to line it one to two days before kindling. Kindling itself is usually brief (15-30 minutes) and most often happens in the early morning hours. Keep the environment quiet, maintain fresh water (nursing does drink heavily), and check the nest once daily without disturbing the doe unnecessarily.
Confirming pregnancy and avoiding false pregnancy
Does can experience pseudopregnancy (false pregnancy) lasting about 17 days, during which they display all the signs of pregnancy including nesting and fur pulling. Palpation between days 14 and 21 is the most reliable low-tech confirmation method: feel for firm, evenly spaced marble-sized lumps along both horns of the uterus. Ultrasound can confirm pregnancy from day 7-8. A blood progesterone test is another option but rarely used in small rabbitries. Avoid repeated or rough palpation, which can cause embryo resorption.

Frequently asked questions
How long is a rabbit pregnant?
The average rabbit gestation period is 31 days, but normal births occur anywhere from 28 to 35 days after mating. Compact breeds like the Dutch and Dwarf typically fall at the lower end (29-31 days), while giant breeds such as the Flemish Giant and French Lop commonly carry to day 32. A litter born before day 28 is rarely viable, and a doe that has not kindled by day 35 needs veterinary attention.
When should I put the nest box in?
Place the nest box no later than day 27 of pregnancy. Many breeders put it in on day 25 to give the doe time to arrange it at her own pace. Fill it with clean hay, straw, or wood shavings to a depth of about 4-6 inches. The doe will pull fur from her dewlap to layer on top, usually within 24 hours of kindling.
How many kits does a rabbit have?
Litter size depends on breed, the doe's age and health, and genetics. Most domestic breeds produce 4-12 kits per litter, with 6-8 being typical. Giant breeds like the Flemish Giant often have larger litters, while Dwarf breeds tend toward smaller ones of 2-6 kits. First-time does (primiparous) usually have smaller litters than experienced ones.
Can I tell if my rabbit is pregnant without a vet?
Gentle abdominal palpation between days 14 and 21 lets an experienced handler feel the developing embryos as small, evenly spaced, firm lumps. After day 21 the kits grow rapidly and the abdomen becomes visibly enlarged. Weight gain and nesting behavior are other indicators, but false pregnancy (pseudopregnancy) can mimic all of these for about 17 days. An ultrasound as early as day 7-8 is the most definitive non-palpation method.
What are the signs of labor in rabbits?
In the 12-24 hours before kindling, the doe typically pulls large amounts of fur from her belly and dewlap to line the nest, becomes restless, and may reduce food intake. She may dig vigorously and frequently enter and leave the nest box. Kindling itself usually lasts 15-30 minutes and most often happens in the early hours of the morning. Keep the area quiet and avoid disturbing the doe during this period.
How soon can a doe be rebred after kindling?
Technically a doe can be bred again within 24 hours of kindling (postpartum mating), but most veterinarians and experienced breeders recommend waiting 4-6 weeks to allow her body to recover and to properly nurse the current litter. Continuous back-to-back breeding shortens the doe's productive life and reduces kit survival rates.
