I have a 3 week old araucana chick that is tailed. I noticed a strange little skin colored growth on its back,above its tail feathers. It's in line with his spine and it resembles a little finger. Thin and about 1/8 inch long. I was wondering if it has anything to do with the fact it is an Araucana and should be rumpless, maybe some sort of genetic boo-boo. I tried to take a picture but its so small and my camera wouldn't zoom in close enough.
