The reddish chicks should be pullets and the silvery chicks should be cockerels.Well my phoenix rooster is starting to attack people. Can't even get in the run without him charging me. He's going to go, but first I'm going to get a few clutches from him x my silver phoenix hen. Is it true that with BBR x Silver they can be sexed by color? Because I have two from that cross and one is silver and one is a pale reddish color. I can't tell if their roos or hens. They both have reddish combs, but I have 12 'sexed' pullets from cackle that all have reddish combs, even though their only 3 months old.
