Earlier today, my Mimi layed her first egg. Celebration! Then sister, Royal, decided to follow suit. Unfortunately, I think I interrupted the process. I opened the nesting box, and saw Royal with an egg half out. I quickly closed it, locked it, and went back later to investigate. No egg anywhere, and Royal walking around, quieter than usual, eating. The coop and winter run are tiny, so I scoured evrywhere, and no egg. I'm worried about egg binding. When should I be concerned? What can I do?
