I am thinking about getting a pair but trying to avoid some of the "issues" I have read. Would having a pair of females work rather than a male/female pair? Would I avoid some of the aggressiveness during breeding season then? Also, I am hoping to keep them to help keep the grass/clover down, so they would be out free ranging with my chickens (and some runner ducks, probably).....does that work? I have about a half acre of mostly grass and weeds. Can add a kiddie pool or something of that sort. 4 foot fencing.
