Yesterday I came home to find that my hens escaped from their run and one was missing. I rounded them up and then found my missing hen. Something killed her - but I do not think it was a hawk. Her entire head and neck was gone and she was opened up from her belly and completely cleaned out. It was so strange. Her feathers, wings and feet were all untouched. Could this have been a raccoon or something. It only got one of 6 hens. This is the second hen I have lost this year and my whole yard is fenced in. Any ideas?
