Need some help with these two girls. They are from my hatch on January 5th, so 4 months old, definitely pullets but I have never seen anything like them. They have black skin, 5 toes, walnut type combs, kinda bearded, regular feathering and are rumpless. Any ideas???? I know they are part Silkie but I have no idea what they would be crossed with that would make them rumpless. As far as I know, the seller of the eggs does not have any rumpless birds. Is this a gene that could have popped out from some other bird? They came from eggs labeled Frizzles so I was told they could be smooth Frizzles but the rumpless has me confused. Thanks for any help you can give!
