How old is she? Flash, it would be helpful to know if the crop emptied overnight, and to watch to see if she is laying eggs. Have you seen any abnormal or shell-less eggs? You can insert a clean finger into her vent 2 inches to feel for a stuck egg, to rule that out. What are you feeding? I would not be giving her any type of molasses or other flush right now, since you don’t know what is wrong. Check her body for any moving bugs (lice or mites or their eggs.) Get her drinking water or some electrolytes by holding a small cup or lid up to her beak often. It might be good to separate her inside a dog crate on puppy pads or a towel to see what her droppings look like. Consider worming her if you haven’t recently.
