This guy popped out of nowhere several months ago and has since taken residence in our chicken yard. He looks like a Hamburg to me, but I can't tell if he's a pure breed and if so, what color. Sorry the pictures aren't that great, I'm no photographer. He's a healthy bird, but it was rainy when I took the pictures, and my chickens don't always have the sense to stay dry, so that why he looks a little glum. Thanks for any help!
