My neighbor lets their roam roam free all day and today she attacked and killed another bird - #3. This one was a guinea that flew out of the coop while we were gone. Normally they are fine out by themselves but not today. What can I do to protect my birds? I'd rather not clip their wings and I don't want to take away from their free ranging time. Now I'm nervous about letting them free range with the neighbor's dog wandering around. There aren't any fences between us and our neighbor's house. Is there a breed of guard dog anyone can recommend? Maybe a fake "shock" chicken to teach the dog a lesson?
