Thanks for all the helpful replies. I took a stick and waved it at him this morning when he came near. He moved away. I told the kids his name is Scary bird so stay away. But I still don't feel comfortable with the kids near. They were holding the hens before the roo got me, and they enjoy that. I've heard roos are tough, so maybe soup. We want to have chicks and are waiting for one of the hens to get broody. The hens we have are red star. Would a silkie rooster mix with them alright??
I don't think waving a stick will deter him forever. I had one that would just attack my DH and after the second spur in his leg, he did away with him. No sense in anyone getting hurt. If that was a child it would have been bad. I have some really sweet roosters and have had a few nasties, all from the same breed so don't think a certain breed or mix is a guarantee of a gentle bird. In my experience, maybe one in ten is a jerk. Just try another, they're not hard to come by.
