racin ~ Yes, when you have a lot invested in various breeds, building Fort Knox will prevent predator attacks and will be a big relief for you and for your flock.It all happened so quickly, I didn't have a chance to react. It was also just getting dark enough that I couldn't get a good look a the hawk. It wasn't huge, so I don't think it was the big red tail that has been hanging around. He's very impressive. This one was small enough that getting ahold of a full size American Bresse Rooster might have been more than he bargained for. But I think they are starting to get more aggressive because prey is less available now.
I took a hint from Too Fast's playbook. Build Fort Knox. The new pens are welded wire fence all the way around and overhead also. Once they are all fenced in (last one will be done tomorrow!) I'll work on covering the bottom sections with hardware cloth to keep out the coons and weasels. I'm also burying some fencing to keep out the diggers also. I'll have 5 separate pens. Turkeys, Bresse, Legbars, Polish/cornish and Laying flock for now. I decided to separate the polish and cornish from the others at the last minute because they are picked on so much. My polish too, Penelope (looong story) will be so happy. He won't have Osiris, my Fayoumi roo, ambushing him every time he turns around. I'll also have Merlin and his girls (the Crested Creme Legbars) all separated in their own breeding group. Can't wait to start collecting eggs from there!
I'm also glad to hear that you're separating the ones who are picked on. I know that it's normal chicken behavior, but that would be a crummy life to constantly be picked/pecked on! They also might not be getting enough food either if the other breeds are aggressive.
Food Pecking Order ~ Since I just have 7 hens and am at home a lot, I make sure that the ones at the bottom of the pecking order get food. I put three bowls of food and two bowls of water in different locations (approx.8' apart). When I bring out healthful treats, I usually use five plates and put them around in different areas of the yard in front of their coop. Then, they start their rotations-- moving from dish to dish thinking that the next one has something better or that another hen is eating too much. When one gets bumped from a plate, there's always one to go to. I watch to make sure they all get some. I realize that this doesn't work for everyone due to size of flock and daytime availability.
