What Michael says is true - Chihuahuas,Doxies and Yorkies are among the "surprise" chicken killers. I never would have suspected them if so many new members hadn't written about their tales of woe. I think a survey was done and the top killers(predators) of chickens was Raccoons and 2nd. was dogs either the owners or the neighborhood loose dog groups. Generally dogs + chicks = dead chickens. You never hear of chickens killing a dog. Mainly dogs and chickens SHOULD NOT MEET.
