I have 2, 5/6 week old chicks (brahma and a cochin-mix). I don't remember my pullets getting wattles at this age. Is it a dead give away for them being roosters? They have staring matches with each other and bump chests. They have reddish combs, but sometimes they seem more reddish orange than red, but there are definite wattle development on both. A pullet wouldn't bump chests or "square off" with a roo, would it? Gah, I just need to be 100% sure they are both roos before I swap them out. I can only find a recent picture of the cochin-mix, he's the black one in the pic. The other "suspect" is at the bottom of the picture, but you can't really see the wattles/comb too well. Thanks!
