What is this?

[Briannafaith]

Has anyone ever seen anything like this? My girl isn’t moving around as much and I finally caught her to check this out. Is it an injury or disease? What can I do to help her?

Currently I have her relaxing in the tub with some warm water after cleaning her good.

Here is a better picture of the swollen part.

Hey looks like a crop all birds have them hers is full.
Smell her breath is it sour smelling? it should go down of its own.

She doesn’t smell foul at all. She just seems very lethargic. I noticed the other girls being mean to her. I was able to get some water down her slowly with a syringe. She isn’t making much noise either.

It seems to be going down after massaging it. It doesn’t seem painful to her when I touch it. It’s extremely squishy.
