Most of my hens like laying in a bush on a hill behind the coop and lately something has been stealing them. Last night whatever is doing it left the shells nearby. I cant figure out whats doing it. They went missing during the day one time.
Looks like damage done by crows to me too. As long as they lay their eggs like that the crows will be back. They are creatures of habit. If you have a game camera, put it up and then you will know for sure. I love my cameras. Good luck...
