I'm pretty sure my easter egger chick is a rooster. I know they are only 5 weeks but "he" named Curry is significantly bigger (and weighs more) and under his chin his wattle is bright red and bigger than all the others. He is actually my favorite and we plan to keep him as long as he behaves.
Also can you tell me what breed the brown and black one is next to him? I have two black ones, one is solid with white on the chest and then her. They said one was a sex link but I can't remember what she told me the other was!
