I haven't read through the whole thread, but I thought I'd mention something. I have a collar on my rooster. This does not hurt him, it simply makes him crow quieter. Now, before you say "That's so inhumane, you shouldn't have gotten a rooster in the first place", he was supposed to be a sexed female chick (so it really isn't my fault). Once I had a rooster I decided that there were a lot of benefits to keeping him, such as having a protector of the flock, the potential for chicks, not to mention just how pretty he is

.
But, we didn't want to hear him crow in the morning, so instead of giving up all of these great benefits, we used a collar. It's working great for us, and while he did go backwards initially (maybe 2 - 3 days?), he quickly got used to it. His hens don't mind and he doesn't either, especially since the alternative would have been soup. One other thing, I am NOT afraid of butchering and eating roosters, otherwise we wouldn't be hatching out chicks. I do like to keep him around though, for the benefits stated above.
Roosters are allowed in my area, but if they are not in yours, then I wouldn't bother trying to keep them.
