Hi, we got a border collie who's now about 6 month old. We live in a suburban area and have racoons, possums, sharp shinned, cooper's, and red tailed hawks, we also have a fox who knows we have chickens. I was wondering if she could possibly deter them or possibly even protect the chickens if need be, we already have a rooster who's very protective of his flock, the dog usually stays away from him, and he's no pushover, chasing off both the coopers and sharp shinned hawk when they had landed and gone after the hens. Is there anything the dog can do as well?
