Hello backyard chicken board. This is my 2nd year raising chickens, and I would really appreciate some help. I have a flock of 12. Half buff orpingtons, and half golden-laced wyandottes with one rooster/cockerel. They are all at 3 month mark, and I've noticed sone behavioral changes. Two of my buff orpington hens are now 'crowing' Is this normal?
