12+ weeks old. No crowing. Slightly pinker comb and more wattle development. feathers on rear look rounded so far, but who knows? Legs look about the same as the others. Same physical size as 'her' hatchmates. I won't rehome him/her until I hear a crow or don't see an egg <g>, so we'll know for sure soon enough. Slow developing roo or faster developing pullet? Sorry about the bad pics - tried to take them IN the coop, but the leghorns are all worked up today and keep trying to fly out . So I got one shot of each of the important spots.
