You can try your local craigslist and local Facebook poultry swap pages if you need to rehome him. Old fashioned posters are also a good way. Be sure to make him seem very likable. If he does not have a name, give him one. Describe any good personality traits he has shown. Get good-quality, colorful pictures of him (a good picture is really worth a thousand words). There are tons of roosters being rehomed, and the only thing that differentiates yours from any other hatchery Oopster is how interesting you can make him seem.
