I have had my losses from the coyotes. The only thing that seems to work here is a big dog. My chickens love my dog. They lay around him under a bush to stay cool and stay safe. He stays out at night even though I lock them up at night. I think he knows that his job is to protect my girls. He gets payed back by getting fresh eggs in his dog food. He loves them as much as we do. The 3 times I have lost chickens and ducks is when my dog was not in the yard to protect them. I have learned to leave my dog at home when we leave. We use to take him with us when we went anywhere but unfortunately he needs to stay home to protect the girls. We are almost done with our new larger coop that we can lock them up in if we need to go anywhere. We usually let them free range. I HATE the **** coyotes. You can not let your guard down EVER!!!
