We purchased 4 straight run buff Orpington chicks back in June and they are about 6-7 weeks old now. I know it could be a little too soon but one of the 4 looks like it could be a rooster. It’s feathers have grown in a little differently than the others and it is the only one with a comb that is this big. Even some of our hens who are a couple weeks older don’t have a comb as big as this one. I know it may be too soon but I just thought I’d see what y’all have to say! Thanks!
