I live in a rural area and a guy up the road from me had hundreds of barrels with roosters chained to them in his yard with many hens running free range. I've hit countless chickens in my car when they run out into the road.
I don't know how their neighbors kept sanity living next to them over the years. Apparently the guy was forced to liquidate his collection recently, apparently the county became suspicious he was raising them for fighting. No other reason to have so many roosters (hundreds) unless your breeding them and even then you would expect to see a sign in the yard advertising roosters and hens for sale.
