Appreciate this article very much. We just went through this for the first time. We have 20 hens and two original roos, a black cochin and a buff laced Polish. We got two young roosters from a broody hatch and they turned into nightmares at about 4 months. It was beginning to change the dynamic of the flock, creating stress for all. We made the decision to cull the two wild men, and everyone is happier. Great article and very useful guidelines, thank you.
