It sounds like she might be egg bound.
I dealt with this a couple of weeks ago.... from what I researched she needs calcium.... all I had on hand was tums/w calcium... I gave her tums water and fed her scrambled eggs with crushed tums, yogurt and the shell crushed up very good. The calcium is supposed to help her pass the egg. You need to soak her bottom in warm water for 30 minutes. We did that while massaging the egg towards the vent.... do not push up into her body as it might damage her organs.... you should be able to feel the egg... grasp from the sides and massage it towards her rear end.
Anyways... none of that worked for us... we even tried to suck the inside of the egg out by poking a needle in the egg... FAIL
Hubby had to tap the egg with a hammer and bust it inside and we put her on antibiotics (tylan 50) for 4 days.... and prayed for the best.
She has since passed the egg fragments and is back outside.... doing well.
