I grew up on a farm..... Had cows,pigs,rabbits,chickens,cats and dogs!! Where I came from, if a dog killed a chicken, it was good as dead. My dad always said once they kill one there is no stopping them. That being said I have both, chickens and dogs now and do not let my dogs run free on our 6...
I recently lost 6 of my 9 chickens and my turkey to a neighbors dogs!! The dogs broke in to the pen... Which we normally had been letting them out, we didn't that day, kept the shut in for safety....some safety!! I can't even go back to the pen!! Now we keep the last three hens in a chain link...
