I left my home for 30 minutes yesterday and upon my return found a fox running away with a hen and 4 dead hens all in one piece and only one with a bit of blood. Could the fox have just killed and then gone on to another flying chicken? I thought dogs did that but we have no free running dogs around. They were all one to five years of age and in very good condition. I was so upset but relieved to find 9 come slowly out of the woods an hour or so later, one is still missing.
