Any advice on how to tell apart? "Rooster" is a bit larger, and has a longer, darker tail feathers than my other Buff Brahma. I would keep him but I'm in a neighborhood and don't need to have a Rooster. I never planned on having one, must have just been sexed wrong. My chicks are 11 weeks old now. If it is a rooster I will have to figure out what to do with him. Any advice is greatly appreciated!
