We have an SLW hen who started crowing today when our only rooster ( White Leghorn ) started learning to crow only a few days ago. He would sound out and then she started to do it. She is the biggest hen and has ran the yard for a while. However, she won't be old enough to lay until August. I've read on here that some hens will crow in the absence of a roo but will one do it as well as the rooster? Or do I have a SLW rooster and not a hen. Is this normal?
