I have a 16 wk old cockerel and some 20ish week old pullets. The cockerel has started mating with one of the pullets in particular (as in, mating ONLY with this female), and I'm curious if it means she is starting to reach or has reached PoL. This is the first breeding behavior I have seen displayed in my flock. None of my pullets are laying yet. Does a randy rooster signify sexual maturity in the pullets as well, or is he just feeling his hormones?
