I have had experience with Jersey Giants, Isa Browns and Golden Comet hens. I let them free range during the day and they return to the coop at night. They are poorly protected by 2 big, lazy dogs. I am surrounded by forest and never had a predator problem (I think because of the dogs). The Comets and Browns were great layers, but I couldn't keep them off the porch. Too much poop! The Giants didn't lay as much, but avoided the porch (the dogs like the porch). I was told it was because they were a heritage breed and therefore more predator savvy than the hybrids. Would Leghorns be a good option? Would they be predator savvy, and stay of the porch? Do white leghorns significantly out-produce the brown, black and red varieties?
