Think very carefully before you breed from your rabbit. The gestation (pregnancy) period for a rabbit is 32 days and a litter can be any size between 2 and 9 so make sure you have good homes for all the possible babies. You will usually need a larger hutch and more food for the rabbit; also consider the added cost of feeding the babies for 8 weeks until they can be homed. Also, during this time, an otherwise quiet rabbit may become very possessive of her babies and her hutch and may not want to be handled.
Bringing new life into the animal kingdom needs careful and responsible consideration. If you seriously want to breed from your rabbit we advise you to get in touch with a breeder and discuss in depth what is involved. Never just mate a doe and hope for the best as complications can arise.
