A local poultry breeder sold me four hens (?). Well, three of them are now very large, healthy, crowing roosters. He isn't interested in buying them back. He will trade for three hens but they are three- years old and he doesn't guarantee they will lay eggs. Now my dilema is what to do with my roosters. I have too many roosters for my small flock and these RIR are very aggressive towards the hens. Sometimes all three will gang up on a single hen. I have asked a couple local chicken farmers but they aren'y interested in them. My wife says they should go in the cooking pot. What is the fastest, most humane way to kill chickens?
