How long is a rabbit pregnant?

Rabbits kindle (give birth) about 31 days after breeding, with a normal range of 28 to 35 days. Does that have not kindled by day 32 may need help or a vet check, because large single kits can grow too big to deliver.

Kindling date = breeding date + 31 days

DayWhat to do
10 to 14Palpate for marble-sized kits
28Add the nest box with clean straw or hay
29 to 31Doe pulls fur to line the nest
28 to 35Normal kindling window
Do not add the box too early. A nest box added before about day 28 often gets soiled and used as a toilet.
