Nothing compares to a good perimeter fence tha contains your LGD. It must be a true flock guardian dog that is born and raised in a poultry yard. This type of set up is an almost guaranteed method to keep predators away from your fowl. As long as the guardian is kept from roaming and he has been raised as a guardian and not a pet. A .380 isn't a good weapon for dispatching predators. You need something with some range. It's not typical to get within 20 ft of something killing your fowl.
