We aren't allowed to have roosters where I live. I actually have twice as many chickens as I'm supposed to have. But my next door neighbor will legally claim half of them if need be.
Update he crowed a little Monday morning and I repeated the process of chasing him every time he did. So he stopped. Hasn't since. My chickens all treat me like one of them. I guess that must make me the head rooster as far as he's concerned. Maybe he will just get used to not crowing if I keep doing it. He's very skittish and all my hens chase him away from food and stuff. Like he's the bottom of the pecking order for sure even though he's easily the biggest chicken I have. I guess the day he realizes he can kick everyone's butt is the day he will start crowing again.
