I've heard this can occur with a new layer. Maude has been laying since June 9th. She laid, then laid three days later and then has been laying an egg a day. When I cleaned the poop tray I found a shell less egg once and assumed another girl was getting ready to lay. However, Maude definitely laid a shell less egg today. They have a good feed, oyster shell and they've had spinach and cottage cheese, raisins and a few other small treats in the past weeks. Is this just normal getting going stuff or am I missing a potential problem?
