This is a random question but one I have had for years. Nobody seems to have a clue what I am talking about. What are those digits on some chicken's wings that look like cat's claws? I had an Americauna that had one about the size and shape of a cat's claw and she clawed me with it more than once, enough to draw blood. I have seen them on other chickens as well. I searched the forum to see if anyone else has mentioned them and I cannot find anything.
