We have chickens for the first time ever, they are now 11 weeks old and we've had them since they hatched. My 4 year old dog loves to chase all things moving - her favorite game is keeping squirrels out of our yard. Now she's taken to stalking our chickens. They are completely fenced off from her with a wood fence that she cannot get through but she jumps on the fence and barks at them constantly. I'm worried all her barking is going to bother the neighbors and stress the chickens. Is there anyway I can teach her to coexist peacefully with the hens? Also - I have considered using cayenne on the fence to keep her off of it but I don't really want to hurt her, is it safe to use?
