I have lost 8 chickens to hawks in my rural area in less then 6 months, with 3 of them only in the last couple weeks. I can't let my bantams out anymore, unfortunately. Some neighbors said they just let the chickens out only in the last afternoon, since hawks like to eat early in the day, so they would go somewhere else. I lost one yesterday at about 7PM

I'll have to keep them cooped up 24/7 now, unfortunately.
Getting a dog and training it to stay with the chickens is a lot of work, but I would consider it. Problem is, my chickens are not next to my house where I can see them; they're hidden away on a hill, so they're just open bait. I'd need the dog to stay there rather than at my front door =) A german shepherd maybe.
The only other option, as of now, is to get some full sized chickens. From what I understand, and correct me if I'm wrong, full size chickens are far too big for hawks. Is that correct? Does anyone know of any regular sized chickens getting picked up by hawks? It'd be good to know before I get some.
