Funny how I can do a search on anything concerning chickens and I always end up at this site! Wonderful. Looks like you've got a similar problem to mine and I hope the BluKote works for you. After the winter, I ended up with six roosters and eleven hens. Had to divide the coops and runs and presently have five roosters off to themselves and one rooster with the hens in another area. I don't know what rooster this one is, medium red with blue-green feathers in the tail that stick straight up, a little lighter red around the ends of the hackles. Big sucker. But even with this ratio, the hens are getting used quite a bit; one in particular is being very submissive, and getting tore up in the process. You'd think she'd plead her case or something. Think I'll try the BluKote too.
After last night, I realize I don't have much to complain about.
