I have this idea to keep dark cornish roosters over rock, orpington, leghorn, EE, RIR.... hens to keep for meat birds. I have heard that they are very good at foraging and protecting their ladies. I am concerned that if I keep more than one I might have fighting roosters all the time. I guess my question is once the pecking order is settled will multiple Dark Cornish roosters calm down and be okay with others around??
