So sorry about Sneaky Chimi. Hope the kids weren't too traumatized. What kind of dog is/was Dozer? He must be very strong to break the chain. I have one dog that is not trustworthy around the chickens at all. Bad chicken dog Belle! Scooter leaves them alone, but I always supervise. He even got attacked by my broody and ran away. Probably would have been a different story if I hadn't been standing right there.
