Can someone please tell me the best meat chickens? I was looking at what they call a rainbow broiler. They can forage with your other chickens. I've heard meat broilers die quite easily. Any info would be greatly appriciated!! Are meat chickens all males or mixed? I just didn't want to start with a chicken that would be a waste of time! I would like something that could forage with the rest of chickens with no problem. (My poor girls with a hole flock of rooster broilers!! UGG!
