I have recently bred my rabbit for the first time and need to know where to put her nest box. She is in a 2 story cage w the bottom of the lower level on grass. She used the bottom part to pee & poop (I replace the sod under it monthly). The top has a divider that allows her one area of totally enclosed space other than an entrace hole. She's already started building a nest in that area. But I worry about the babies falling down the ramp once they start moving around and I can't really close it off without mama not being able to go to her preferred litter area. So should I put a nest box in the bottom area, add one to where she is already nesting, or just let her go with what she is doing as the enclosed area is basically a nest box in itself? Thank you to anyone who can help me.
