Our flock of eight hens used to give us six-seven eggs a day. Now we get one-three eggs a day. It was a mystery until this morning our oldest hen was caught rolling a egg out of the duck pen. Later we found a broken duck egg with all the contents eaten. In the chicken pen. We think our chickens are eating their own eggs too. They have a pen with greens to eat and setting up a TV to keep them entertained is sadly not an option. Any ideas for identifying/stopping the egg eaters?
