If you happen to have a pair of rabbits, no doubt you will probably want to raise a litter.
The first thing you will need is a proper nest box. You can put about 2" of pine shavings, then shredded newspaper or computer paper, for the doe to kindle in. The pine shavings is optional.
Thirty to thirty-one days after breeding, she will be ready to have her babies, so you must have a nest box in her cage about 2 to 3 days before her due date. Make sure she has a cage by herself and she will take care of the rest.
A nest box is just a simple wooden box made from scrap plywood, (never use treated wood). The measurements can vary according to the size of your rabbit. For most Californians, make your box 18" long; A dwarf rabbit will only need a small box made to fit her size.(Making the nestbox about 1" bigger then your doe on all side)
Add a little 6" - 10" wide shelf to the back end of the top as a resting spot for the doe, she will love it!Put screws in from the top,this may give a little more support to the box, but be sure it is even with the sides so you can put it up against the side and back of the cage.
