I have to say I know your frustration, I have had problems with my Own dogs ! I am a dog lover all my life and also love my chickens, so I'm afraid I can't agree with most of the post to SSS ! I would however warn the owners that if the dogs come on your property again that they may lose their dogs, not by killing of course, but I would be on the phone right away with the dog warden/police whomever it is you have to call to have the dogs Removed.I would Never live like that, having to check constantly on your chickens making sure a dog isn't killing them, that just is not right to make you live like that. They Need to keep those dogs off your property, let them fence them in their own yard...Untill I had chickens I prob would think differently, but since my own dogs whom I love have killed a few of mine, I now know that Some dogs will act like dogs and it is instinct. They're gentle with all people, cats etc, but don't let a chicken get out into the yard where they are, they can't control themselves. Meanwhile they will lay with their backs up against the chicken yard with chickens scratching right behind them and pay them no mind at all, but if loose, watch out.....I have just made sure my chickens are totally enclosed in a very Large enclosure and all is well. But I know the heartbreak of a chicken being killed......So let the law be on your side and call the humane society or take the dogs there yourself the next time they come on your property, Do not put up with that !!! Good luck
