I woke up this morning to find one of my hens who was sitting on eggs missing and her feathers all over the yard. I feel horrible because the coop was left open because another one of my hens went missing 2 days ago from the yard so I left the coop open in hopes she would show up. She had never been outside the coop alone at night so I left it open so she could go back inside. Now I realize what a horrible mistake I have made. Does anyone have any advice on how I can catch what is killing my hens? A neighbor down the street has also lost 2 hens this week. I could keep them locked in the coop at all times but I would like to catch what is killing them so I can stop worrying. Any help is appreciated. It's a very sad day here.
