Well, unfortunately my dog got to 6 (out of 8) chickens! They were only 4 months old and he had never expressed any interest in them! I had planned on making my coop more predator proof but for 3 months, they were fine. So, my own dumb fault. Anyway, my dog is so hard to contain and he has already gotten a neighbors guinea so I know he runs off and is a pest to all my neighbors. My question is what do I do with him? I do not know how to train him (Obviously!) We have 5 acres unfenced and he is used to running around loose but he does run off. I have had it and am willing to contain him. He is totally huge and could be a danger! I had my husband put up one of those runs that go from tree to tree about 40 feet and then there is a lead off that so he has about a 10 x 40 ft space. He is handling it well but I feel bad. What I am really wondering is if we kept him in the fenced back yard, could we bury an underground fence just inside the chainlink and contain him? He is freakish about storms and when he is in the back and wants out he will just dig under. There are railroad ties and concrete block all along where he has dug and it doesnt stop him. Has anyone tried an underground fence inside a chainlink fence? Thank you!
