How common is it for silkies to have the wrong number of toes or partial toes? What would cause this? I have one with a tiny dangly toe nubbin. I almost ripped it off because I thought it was poo. It has 5 toes on the other foot. I have one with 4 toes on both feet and one with 5 on one and 4 on the other. On the 4 side the 4th toe has a seam on the end and 2 toe nails. Will I be able to breed these or will the toe thing be passed on genetically?
