I have a 20 month Rooster and 7 hens. My rooster has become very aggressive when I come into the run to change out water and add new feed. I've tried being forceful with him to show who is boss. Nothing has worked and it is only getting worse. I enjoy raising and taking care of the chickens, but this is spoiling the enjoyment. What are my options? Is there places in Colorado that take roosters? thanks, John
