We've had chickens for several years and have not had predator problems until this summer. We had regular chicken wire around the perimeter of their yard (40' x 60'). their 8' x 8' coop is within that area. Four times we have found a decapitated bird in the afternoon. From what we read, we though weasel....so we tore down all the fence and replaced it with buried 1/2" x 1/2" metal fabric fencing. All seemed good for a week, but today we found another dead bird. Same story, head cut off. I'm thinking about bird netting over the entire area now.......will that work? I don't know if it is a hawk or if something is climbing over the fence......but it happens during the day. Ideas?
