I just went out to collect eggs and one of my big girls was dead next to the fence in their range area. She was fine earlier. Something killed her and had eaten her in her belly. I just burried her. I wished I had taken a picture. I didn't see any tracks. I saw a crow out there earlier. I just put them in their run and locked the gate. I just set up the critter cam. It is zero lux but I put a light out too. I lost another girl last night time for the critter cam again!!!
