How do you keep track? Is she the only hen in that pen?
Actually that year she was in with a 3 year old hen who was laying for the first time. The 3 yr. old is a white and her eggs were obviously smaller and a shade lighter in color. My Pied also lays eggs with calcium deposits on the shell, so there are little rough spots on her eggs and they are very clearly visible when you candle. Bottom line is I can always spot her eggs in a bunch, a lot of the others I cannot tell apart.
