I would separate her today to watch her, and put some paper towels under her to catch droppings. But keep her warm, so if you cannot separate her, just keep an eye out. Get some Poultry NutriDrench and give 1 ml daily. Make sure that she is eating and drinking. Look for diarrhea or bloody poo in case it is coccidiosis. Other signs of coccidiosis are lethargy, standing hunched, and weakness. She may have been hurt or pecked, and she may be fine, but you will need to watch her.
