I had 3 hawks in my yard yesterday....hanging out in the trees waiting for the chickens to be out.....I'm considering getting a Great Pyrenees .....does anyone have any experience with them? I have an acre fenced, I'm not sure that is enough. I cannot shoot the hawks......its illegal in this county. They sure will ruin a chickens day. On the flip side being confined to the coop for days on end made my old girls learn to like our new little chicks, the pecking order has stopped and now they are like old friends!
