Poor girl, she is not feeling well. Can you gently do another exam to see if you feel an egg? Getting a fecal float to check for worms and coccidiosis is always a good idea, as well as, checking the crop to see that it's emptying overnight. From her stance, the abdomen feeling fuller and with her being like this for a couple days, I would lean toward a reproductive disorder. IF there is fluid in the abdomen, sometimes that can be drained to give short term relief along with antibiotics to help fight infection.
