I have been letting the chickens run around I. Our yard during the day. For the first few weeks, I would lock the doggie door and only let them out for a couple hours. And during this time I would take the dogs out on a leash to get them used to the chickens. They were behaving so well. So a week ago I decided to see how they were off leash. They did awesome! Didn't chase the chickens or anything. So the past couple days I have let the chickens have free range of the yard and the dog door unlocked. And no problems. Well today, at 6pm. I went out to check on everybody and my dog was chewing on a carcas of one of the smaller chickens. No head. No blood anywhere. And I don't see a bunch of feathers anywhere. Could it have been my dog who killed it? I'd hate to have to lock them up when the chickens are out. They've done so well the past few weeks! Btw my dogs are Pomeranian chihuahua and Pomeranian dachshund ( the one chewing on the dead chicken )
