I couldn't find a picture of his butt, but his feathers are starting to fall over and he's got some darker ones in there. Him and my rooster don't get along...and I'm not sure they will. :(
I bought this gal/guy hoping for a hen, but I have a feeling - with the streamers - it's a rooster. Personality wise, he's the lowest in the flock and the other rooster (very obvious a rooster) picks at him. He's very docile.
