Is there a certain standard size breed of roosters that are known for not being overly aggressive? I have had bad luck with 2 now, one being a beautiful Cuckoo Orpington and now my Production Red seems to be turning on me also. My bantams are ok and kept separate, but I want to have a standard size for my 17 standard hens. Breed doesn't matter that much at this point, just don't want to constantly be watching my back, as I am very active with my chickens. P.S. It's not a crowding issue, they have a very large area. We live on 55 acres.
