I have a general question. My flock consists of many variety of hens, (see signature line) and I have 3 black cochin roos. Three weeks ago I hatched 2 chicks, 1 black, 1 yellow, but is now feathering to mostly white (I don't have any white hens) I just hatched 10 new chicks last night, all a variation of all black. My question is what about the white one. Could it be a roo since roos are typically lighter in color? I can post pics if necessary, but it is only 3 weeks old, is this too early to sex?
