Rabbit gestation calculator
Type the date she was bred: the kindling date, the likely window and what to do before.
Rabbits carry about 31 days — about 4 weeks. Most have their kits between day 28 and day 35 after breeding.
Date bred
The day she was with the buck.
Pick the date she was bred to see her due date.
Example: a doe bred on September 1 is due about October 2 — most likely between September 29 and October 6.

Questions
How long are rabbits pregnant?
Rabbits carry about 31 days — about 4 weeks. Most have their kits between day 28 and day 35 after breeding.
How do I work out a rabbit’s due date?
Add 31 days to the day she was bred. Example: a doe bred on September 1 is due about October 2 — most likely between September 29 and October 6.
Why a window and not one day?
No two rabbits are the same. Most give birth between day 28 and day 35, so start watching her at the beginning of the window. Small breeds tend to kindle a little earlier than heavy breeds.
What if she was with the buck for weeks?
Enter the first and the last day they were together. The window then runs from the first day plus 28 days to the last day plus 35 days.
