My dog just went crazy at the door... he seems protective of his chickens though I have never allowed him near them once they left the house (he growls at the woman who lives above our barn when she is near them, though he loves her normally)... Low and behold there were two healthy looking cats creeping along the fence toward the chickens. As I ran out there they moved a little further into the woods, but the CHICKENS continued to follow them. I threw rocks and the cats ran off... Will they come back and eat my girls? They are six months old. But I have a polish and a hamburg (which are smaller). I am concerned! Thoughts?
