I've just always felt better about the homes I've taken roos to. I think I got a bad picture because of all the rain we get here, and the guy seemed very sweet with his animals. It wasn't bad. Access to a large run, a big coop with heat, and lots of other chickens, duck, turkeys, goats, mules, horses etc. He is a hatchery and does a lot of business. He laughed at my concerns a bit and said he would be well taken care of.... so I'm probably just being paranoid. I saved the roo from a cat attack as a chick and nursed him back to health. He was spoiled rotten and trained to fly onto my arm for treats, but, like you said, I have to think of my flock, and he was being very rough with my hens.... he has ripped out a bunch of their head feathers and made my little cochin banty bleed. I'm pretty sure my hens hated him..... and I have a very sweet D'Uccle roo, that is quiet, goes to bed early, wakes up late, and does not beat up on my hens. I won't have as many fertile eggs to hatch, as my roo is tiny and I have 20, mostly full sized hens....
Oh well. I guess I did what I had to do.the DH wasn't having it anymore. I need to be grateful I can even have one roo....
