My buff Orpington is a little over a year, she's normally a good layer, however, about last month she stopted laying. We figured since it was getting hotter she was just taking a break. She has become egg bound and passed two parts of an egg seperatly yesterday. We have been bathing her, today she layed a no shell egg in the yard. I can feel a lump around her vent and it is swollen. She's back in the nesting box now, what can I do??
