I am guessing that I have at least two roosters in my batch of chickens that hatched out in September. This one is a cross breed and I have no idea what breeds it could be--I got the eggs from a friend. It's larger than the other chicks and very aggressive. It looked like a vulture for a long time because it's head feathers did not come in until way after the rest of its feathers. It frequently challenges my near full-grown chickens. These pictures are not very clear, unfortunately, but at least one has "Vulture" next to some of its siblings. The comb is much larger and redder, and the wattles, which are still fairly small but growing faster than the other chicks, are very red as well. I don't know if that means anything or not.
