I have three buff orpingtons and three cuckoo marans. The buffs I think are three hens and two of the marans look like they may be roosters. They have much longer tail feathers and seem to stand different than the others. They are 8-9 weeks old. Is this to young to tell? One of them keeps flying up and sitting on my shoulder and seems more dominant. Couldn't take pictures today because it's pouring, but I'm curious if there is any other way to tell at this age.
