I really like my rooster. But he'd be the first to run for cover if a real predator came around...lol. He does give warning calls, but so did my lead hen before the roo came along. Some roos are self sacrificing heros and some roos aren't I guess
My girls eat very little layer feed during the nice months. I notice them eating more as colder weather begins setting in, when the grasshopper and other bugs begin to die off (or hibernate - whatever insects do) and the grass starts to die. Just enjoy the low feed costs for the warm months
