Losses happen when you have chickens out in the open. If not a stray dog than a coyote or fox. I’ve even seen a raccoon do it. Even if you manage to deal with this stray dog, there’s gonna be another stray dog. You can’t lose your head about every little thing.

The option to take possession of and then rehome the dog was not afforded to you by law. If you’re going to use Nuisance dog laws you your option is to shoot the dog, or turn into animal control. If you want to choose a happy fate for the dog and keep your chickens, you have to do the hard work of working together with your neighbor to understand and fix the problem, even if they’re an annoying drunk.
