We came to this conclusion - maybe she was eggbound and everything inside had been getting blocked up behind this trapped egg, causing it to ferment. Then the gases from the fementing food found that the only way to escape was to go back up the pipe, causing the crop to fill with gas. May not be accourate, but it's all we could think of.

We lost Bluebell in the late ours of this morning..

RIP Bluebell.
