I did a search for this but couldnt find it: Can I definitively sex my 13 wk old chickens? I read on another thread that if they have pink comb at 10 wks (as mine did) then they are roos. Noooo! We cant have any roos here and hate to think of dispatching any of them. We have White Leghorns, BRs, a Golden-laced wyandotte, and a Turken. Only the Wyandotte has no comb at all. Any way to find out more?
