theyre right, he views you as at the bottom of the pecking order or as a threat to him or the girls. You CAN get 'rid' of him, some people don't want to or have the time to deal with the more aggressive roosters. But heres how I see it. The rooster is supposed to be the protector of your hens, thus he needs a certain element of aggression in him in order to do his job right. How would you feel if a coyote came into your flock and started killing all the girls, and the rooster sat back and did nothing? No bueno. Id get rid of THAT rooster. That is truly good for nothing. He needs to defend the flock.
SO with that said, there are many methods to help your rooster to become submissive to you. They require time on your part, but if you have time then these may work. No guarantee. Depends on you, depends on the rooster. My favorite is to approach the rooster- with confidence. They can sense fear, like horses...so you need to not be afraid. Scoop him up and carry him. Hold him. Do your chores while holding him. Walk around the yard and hold him. He may resist at first, but eventually he will submit. And he may start to like it. This is the best method ive seen so far. They become submissive to the individual who does this. But its no guarantee. And you need to put time and effort. And make sure you protect your arms and body from him talons the first few times you do this, he may try to fight back. Just remember youre in charge, youre the alpha predator and you are stronger.
Good Luck! I love my Roosters!
