Look into a Cubalaya line that has been free ranged. I have stock that is very predator savvy. 15 years ago I started a project to get adept free rangers with my Cubalaya. The first year I lost almost unbearably too many (we lived in a hawk migration route) I did allow it to happen though. The survivors got to breed and now I seldom lose any to hawks. I do have a Great Pyrenees now, but I didn't have at first. I purposely gave them cover to scatter into when needed.
Seven years into the project I timed an incubator hatch of my project chicks to a hatchery order to see if my project is doing what wanted it to do. I put both my incubator chicks and the hatchery chicks in the brooder together (same age), waited until they were 1 week old and then simulated the scream of a red tailed hawk to the chicks. All of my project chicks scattered to the corners/outside edges of the brooder and flattened themselves to the floor. The hatchery chicks went about the business of eating and drinking as though nothing out of the ordinary had just happened. None of these chicks had ever been with an adult experienced hen to be trained. This experiment tells me that chickens can be bred to retain hawk savviness genetically. When free ranging I always have given them cover of some sort to slip into or tall perches to fly up onto for the ground predators. Every year I have birds that I get rid of because they don't meet breed standard in some way, shape or form. I am willing to help you with some birds if you're interested.
Blue red cockerel will get pretty big.
