I've got a couple golden laced wyandottes that I'd like to sex. We swear we've heard one of them crow, but we're hoping we at least have one pullet! As far as I can tell it looks like one of their tails is a little more flat and the others points up. And maybe one's comb is more red than the other?
Only pullet is on far left. Welsummer?
