I have 3 gold sex links and 1 Buff orpington. One of the sex links is the alfa female, I suspect she might be a rooster. Her comb and waddle is very defined, the other 3 girls have very small combs and barely a waddle starting. But she does not have a dew claw or (spur) and she hasn't crowed yet. I have heard that even the alfa female may even crow. Is this true.......?
