Not at all.Anyway, I think I thought you were saying any dog that even chases chickens at all or kills by accident was a bad dog. That’s part of why I was saying I don’t think that alone makes a bad dog or warrants death. Sorry, misunderstanding I guess.

Shoot, my awesome dobie/lab chased a chicken the first time he saw one. Once.
Same with the street rat. I do understand that it's instinct, and is stronger in some breeds than others. Training is required.
These specific dogs destroyed two coops/runs and killed two flocks of birds within a couple weeks. Who knows what else they did in that time period. I sure as heck would never want a dog like that and I doubt anyone else would either.
