My cockerels were hatched in March. We got straight run chicks and ended up with 7 cockerels. At first we considered giving them away or eating them but "chickened out". They are all beautiful and different colors and patterns, sizes, etc. We have a farm with llamas and goats and the roosters just free-range at this point. So far, no losses to predators and they have been an enjoyable addition to our farm. I've had numerous people warn me that our roosters were going to "get mean". I have been dilligent to make sure they know who's the boss. Last week, our head roo Milford, "accidentally" ran into my daughter (who is 5). I chased him around and picked him up just to be on the safe side. Well today, while she was throwing cracked corn, he went after her 3 times with his feet! I chased him around and then made her chase him several times. He flared his neck feathers up at her but a little kick with her rubber shoe and he backed off. I don't want him to hurt her. He is a beautiful Delaware. I hope that once he gets the idea that she is the boss, he will stop his crazy behavior. Just two days ago they were "playing" side by side. Is there any chance he will mellow with age? Will he get over his napoleon complex and understand that humans are not to be messed with? BTW these roosters do not have any girls. I have all the pullets in a coop/run with one little rooster, so the girls don't get picked on.
