My birds free range in our suburban MA yard. There is a 5' chain link fence surrounding the entire yard and there are bushes, shrubs, etc along the perimeter. Two juvenile pullets were being introduced to the flock of young mature hens, but I lost one on Tuesday and one on Saturday, both around the time I went to close up the coop and hen house. Here's what I know, both happened the same way: Dusk/early evening Pullets were taken to the back of the yard, but not out of the yard Found lots of feathers, the head and the intestines, plus the croup- nothing else What am I looking for? And how can I let them free range, but keep them safe??
