ok, i know this post may get taken the wrong way by someone but it's really only a half serious question. you end up with 13 roosters in an area where they may not be very welcome and all of a sudden 10 of them learn how to crow in the same week. i wasn't planning a huge slaughter and quite frankly, i'm gettin tired of rooster. Until i figure this out... can u train them to shut up? how does their mental process work?
