Well, Congrats. Now you have to make some decisions. You can`t let the other girls add to her clutch, so you either have to mark her present eggs and remove the fresh ones daily, or you have to move her to a private location, away from the others. I preffer the private location for the simple reason she needs to be moved to ground level, anyway. Why, you ask? Chicks cannot enter and leave an elevated nest. So, if and when you move her, do it at night with as little stress as possible. That way she will wake up in the morning and all should be well. Good luck..........Pop
