I feel odd asking because I usually have an answer for just about anything rabbit. I have a doe (a NZW) who with every litter kindles about 9 perfectly healthy kits and then 2 or 3 underdeveloped ones. These kits seem to be maybe 2 or 3 weeks into gestation. Why does this happen? None of my other does do this. We breed by putting the doe in with the buck and wait until we get 2 or 3 fall offs and then wait 8 hours and put the doe back in with the buck and wait for another 2 or 3 fall offs. We do NOT put her back in with the buck again after 2 weeks specifically to prevent a double pregnancy or underdeveloped kits. Is it possible that she is aborting these kits part of the way through gestation? These are not placentas or afterbirth, I am familiar with those. She is fed well with good quality pellets, hay, and clean water. She is not too fat or too thin, and she is the only doe of mine to EVER do it. She is from a new line from an outside barn, an unfamiliar line to me. Is this genetic? If I were to keep one of her kits, would she do it too? I have been debating on culling her (and keeping one of her kits) because of this. She isn't super friendly but she doesn't bite or scratch or lunge, so I've kept her for almost a year now. Would she stay or go in your barn?
