I live in a small (pop. 1000) rural town. I started with my chickens last year with 50 heavy breed birds. I had about 20 roosters that I processed at about 18 weeks. The reason I processed was that they had started crowing. 20 teenage roosters was more than even I could handle. Nobody complained, but they had the right too if they wanted. I kept back one Delaware. He crows several times a day. Then about 7-8 months ago, I began hearing more crows from different parts of town as others joined the backyard chicken revolution. My point is, don't be abusive with your roosters (which it doesn't sound like you are) and more than likely, you will begin to hear others as more people begin to realize the benefits of eggs, fertilizer, etc. Plant the seed or in case grow your birds, and see what grows from it. I like selling my eggs, but I would rather have other flocks around, it gives me something to talk to my neighbors about other than the weather!
