I have, in total, 11 laying hens. Five Barred Rocks and six White Leghorns. They've been laying around 3-4 eggs per day, and I'm wondering if they are eating their eggs, particularly the Barred Rocks, as today I saw my Black Sex-Link eat what looked like a piece of brown eggshell. I never give my chickens eggs to eat, so I'm not sure where they could have picked up the behavior. I don't think it's consistent, perhaps just one hen is doing it. I know that you're supposed to collect eggs several times a day to prevent egg-eating, but I'm too busy to do so, collecting usually at around four o' clock or later. Any ideas of what I could do to stop it?
