Aggressive rabbit-4 kits but 2 died

My rabbit had 4 kits but two died, and she doesn't seem to be taking care of the other two. Also she keeps stepping on the two still living. It's really cold and the kits are outside of the nest what do I do?

Oh dear, doesn't sound good. Quick, put the kits back into the nest, and pull some more of the doe's fur so they'll stay warm. Arrange the nest so the kits are in a hollow and can't just crawl out. Your doe is acting like she doesn't realize those are her kits. My fear is that the doe's instincts have not kicked in, and you may lose all the kits. There's also the chance the doe did not inherit enough maternal instincts.

You can only do what you can do -- let nature take its course and rebreed the doe if the kits die, or you can try hand-feeding the remaining kits, supposing the doe doesn't figure it out in the next 24-36 hours.

Good luck,
