I've sold or given them away. I place ads on the local equivalent of Craigslist. I've been given a list of people who will buy excess roosters to eat, but thus far I haven't needed to call anyone.
I too put an ad on craigslist. I was surprised at the numbers of calls I got (probably because they were "free"). Folks assured me these guys weren't going to end up in freezer camp, although, of course, I have no idea what happened after they left my home.
i give them away for free or let them go when there older out by a stream and kinda a foresty area i live by. my roosters are still living there. heathy but not friendly.
