Thanks for the reply it was very helpful. Its splay legs. They are not close to being 3 months old and the description in the link fits. I only have 3 rabbits, one buck and 2 does and this is the first I have seen of it. The two Does are sisters and bought from a different place than the buck...
This doe and buck have produced 3 other litters and this has never happened before. She had a small litter this time (5) and only 3 lived...but they all drag their back legs and the legs are utterly spread out? Almost like paralyzed from the waste down or something? I have had rabbits for a year...
