How it is calculated

  1. Start from the breeding date. Use the date the doe was bred. If the doe was bred more than once, use the last date.
  2. Add 31 days. The average doe carries for about 31 days, so the due date is 31 days after breeding.
  3. Mark the normal window. Most kindling happens between day 28 and day 35, so watch from day 28 and call your vet if nothing has happened by day 35.

Questions

How long is a rabbit pregnant?

About 31 days, usually between day 28 and day 35.

When should the nest box go in?

Around day 28, so the doe can pull fur and build the nest without soiling the box too early.

What if she has not kindled by day 35?

Call a vet familiar with rabbits: a doe past day 32 to 35 can carry dead kits, which is dangerous for her.
