Yes he is! My dad told me he was getting aggressive but I didn't realize just how much. I've been trying any tactic I can read about but he's mostly just been getting sneakier. At one point I bent over to move the feeder and he ran away from all the hens milling about 8 feet outside into our coop and attacked my head, breaking skin. I want to be able to keep him and think that I did the best I could, but the more I read the more I feel like many people recommend culling or getting rid of aggressive roosters if they are causing issues, especially since I'm not very experienced and don't know if I can ever truly get him to knock it off.
