I currently have 12 chickens, three of which are silkies. My hopes when I ordered them was that I would get at least one hen. I'm pretty sure that's what I got--one hen. I know for sure that one of the others is a roo, and I suspect that the other is (although he isn't quite as big and has never crowed). So far, the two don't seem to have any issues with each other, but I'm assuming that will change, right? At what age would they start being aggressive with each other (they were both hatched on June 14th)? With ten hens, is there a chance that they would tolerate each other? They don't free range (too many loose dogs, hawks, racoons, foxes, and coyotes in my neighborhood) so they can't get away from each other. I'm trying to decide whether I should wait and see how things go, or start working on a home for one of them now.
