My lop bunny has had babies, I peeked and see two. Could be more. I've never seen her with them, but it's day 6 now and I do see movement in the bed. She's covered them in so much fur it's hard to see them, and I didn't want to uncover them. If theirs one that died, do they take them out?? What happens? I read that they only nurse twice a day, so I guess I've never caught her, hoping she is. Is it ok to pick them up and check on them?
