Try in your state page here. Re-homing roosters is very difficult. And once they are no longer yours, you don’t get any say.
You might get lucky, but it doesn’t happen very often. So then people are tempted to keep them, hence the post above. But that has it’s own set of problems, especially in a small flock, in a back yard set up, especially with a very dominant bird, which is what your boy is showing. They are not like puppies, where curiosity and friendliness is a good sign.
You can also post at the feed store, Craigslist, or join into a poultry club. Sometimes 4-h kids will take one. Check out the county fair.
My advise is enjoy him now, but know that he is going, and don’t ask any questions if someone is willing to take him.
