I have a 9 mo old roo and 2 hens. About a month ago i integrated 17 - 8 wk old chicks. 3 cockerels and 15 hens. They are now 11 weeks old. Things have been going really well but i noticed the roo, who had previously mostly left them alone unless they got in his way, is now starting to "herd" a few of the girls. I call it herd, but i know most call it "the mating dance" but this guy doesn't do it to mate, he does it with the older girls, when he wants them yo do something or if they do something wrong. Example, coming out in the morning, if they come out and run to drink, he will go after them (he always let's them out first) to make them eat first. He has started taking notice in the young girls and getting them to do the same. The other day i noticed one of the young roos crowing. He is also starting to stand tall and showing some "im the boss" attitude. So it go me wondering, at what point do i need to separate them (the roos) so i dont come out one morning to a dead bird? Are there any signs i should watch for?
