I know what it is to love a sweet little rooster. I also know what it is like to rehome him with a nice family. Do it. You won't regret it. When I had to rehome my rooster, I thought it would be like when you lose a dog. I thought I would miss him every day. What I have discovered is that a flock is sort of an entity unto itself. So when I rehomed the rooster, it just made for a happier flock. I wasn't looking for that one chicken (the roo) as much as I was loving my time with all the chickens.
You just never know how terrible & stressful a situation is, until you give yourself a break from it!
