my daughter has 8 little banty hens. when i got home from work 6 of them were dead around the back yard. My yard is fenced and gated. I have a boxer (which in two years has never bothered them) and am now taking care if my deceased fathers dog which is a retriever/lab mix. I have only had this dog for two weeks but it has not bother the hens. The dead hens were not missing any feathers and were whole except for 3 which had there stomachs only ate. Neither dog had any blood on them and my dads dog was with me when i picked them up and did not show any signs of guilt, or was territorial or anything. He just sniffed the bags and walked away. My husband is convince that he is the one that killed them but i am not. I need some opinions on whether this is typical dog behavior to kill and eat only the stomach or if i should be looking for a preditor.
