I purchased a straight run this spring of Rhode Island Reds. My fear is I think I got 12 roosters!!!! I usually can tell the difference by the size of their legs/feet, comb, and tail feathers. But I am really stumped with this gang of juvenile delinquents. Is a RIR hen comb really small or can it be almost the same size of a rooster? My chickens are approaching 5 months old and have some major ugliness between the reds and my 3 younger orpington hens. I actually fear for their lives. I know I have to do some butchering immediately but do not want to dispatch hens by mistaken identity. Although the chorus of crowing is very entertaining! They got to go!
