We have a very nice Border Collie that loves being around chickens. We have been going through a lot more feed then normal and installed a security camera system in our barn/coop/run. To our surprise our dog comes down and eats there feed right after both of us leave in the morning. Our chickens are free range, and we will be keeping them that way. We have the run fully enclosed except for a small door that the chickens come/go as they please. He is squeezing through that door.I installed a strand of electric wire just below the top of the door, but he apparently is not getting hit by it. Any lower with the wire and im worried that chickens will hit it. Any ideas?
