So we have learned that the egg song doesn't necessarily mean someone has laid an egg. It has various meanings: I have laid an egg, I am going to lay an egg. Someone else has laid an egg... And my favorite - I need to lay an egg, but you are in my favorite nest box so hurry up and get outI heard a bunch of egg song (from 2-3 hens) this morning but no eggs in the nest box

And then I think this is the speckled Sussex

Breaking an egg open is pretty messy. I don't think she could be eating eggs in the nest box with out leaving evidence.The sapphire gem was in there all morning. No egg. Did she eat it?
