During the day I let my ducks, guineas, and chicken free range... I breed silkies and they attack them all the time! How do I stop my guineas from attacking my hens? Their vicious and if they don't stop I'm gonna shoot them.. I don't have the guineas penned up they fly out over the run all the time but they won't leave (kinda hoping they would.. they just run the fence line) but they keep comming back... UGH! they are fun birds but I can't have them attacking my hens.. what can I do about that?
