Rabbit Gestation Calculator
Rabbits have one of the shortest gestations in the barn: about 31 days, with most does kindling between 28 and 33 days. The detail that matters most: the nest box goes in around day 27–28 — too early and she soils it, too late and kits may be born on the wire.
Typical management windows for planning — health decisions belong with your veterinarian.

Common questions
How long is a rabbit pregnant?
About 31 days. Most does kindle between days 28 and 33 — if a doe passes day 34 with no litter, consult an experienced breeder or vet.
When do I put the nest box in?
Day 27–28 after breeding. The calculator above dates it for you. The doe will pull fur and build her nest in the final day or two.
How can I tell if the breeding took?
Experienced breeders palpate gently around day 10–14, feeling for grape-sized embryos. A test breeding around day 14–16 (a pregnant doe usually refuses) is a common backup check.
How soon can a doe be rebred?
Commercial operations rebreed quickly, but many backyard breeders wait until kits are weaned around 5–6 weeks. Match the pace to the doe’s condition.
