Hello my girlfriend and I just recently started raising bunnies and we have had a few litters without any issues so far. Until this last litter anyway. We mistook one of the newborns genders and ended up sticking a Male with 2 females. Mother and sister. Anyway he ended up getting them both pregnant. The litter with the mother turn out fine we had 7 healthy kits. I know this is called linebreeding. However the inbreds between the brother and sister didnt come out healthy at all. We had 3 of them and I have been nursing them from the beginning. Within the first few days 2 ended up passing. The third which was the weakest in the beginning has survived however I am concerned for him as he has a birth defect. Some of his toes on his hind legs were born black and are rotting off. He doesnt seem to be in pain and is healthy. He eats well I just really would not like to lose him. I cant find any sources online about this. I dont have money to visit a vet. However I have made a peroxide solution that is 1 part peroxide and 3 parts water. I know it stings but I have to keep it clean somehow. Please help. I have grown so attached to this darling baby and he literally refuses to sleep unless he is with me.
