Well... Not exactly strays, they have an owner but he just lets them run loose... They aren't nice to humans either... The dogs, anyway. I do call the police when chicken killers come around.
Forget the police; they got other fish to fry. Call Animal Control if you don't want to handle the problem yourself
The police got aholt of AC and removed 2 other killers.... Good thing too, cuz those ones knew I had chickens...
