My easter egger has been sitting on eggs for around 2 weeks. Everything was fine, then today I saw her eating out of a broken shell. I couldn't tell if it was a baby chick or just an unfertilized egg. It was dark in the coop and I didn't want to pick her up and disturb her. Is this common? Do broody hens ever eat their babies? This is the first time any of my hens went broody. I don't know what to expect. Should I worry that she'll eat other eggs?
