It could just be a bad time of year for rehoming. Everyone who hatched chicks in the spring is trying to unload roosters right now as well. You may have better luck later in the fall when there’s less supply? I had to rehome a rooster last fall, and it took about a month to get any legit interest on Craigslist, but was worth the wait as I’m confident he went to a good home.I've been trying. I don't know chicken keepers personally and I've had no takers via various FB groups and Craigslist.
