I have two rabbits left out of one of my NZWs litters and when they were born (two months ago) I looked all of them over carefully and thought they were all normal and everything but this morning I noticed one of the rabbits is missing one if it's back feet. It isn't an open wound or anything it has fur on the stump there is just no foot there. It gets around fine and appears to be healthy but I am not really sure what to do with it. Should I go ahead and try to sell it? Give it away? Cull it? What would you all do with it?
