Hen has fluid in the breast area

[Lindeez]

One of our hens has fluid built up in her breast area. No sign of trama or mites. She nods her head awkwardly and has a deep cackle. She quit laying a week ago. Her appetite is good

Can you post some photos of her?

Is it the crop you are feeling? She may be having some crop problems where it is not emptying completely overnight. The head movement may be from trying to adjust the crop.
Look at the video in post#1 of this thread-does she move something like that? https://www.backyardchickens.com/threads/weird-neck-movement.1246236/#post-19994524

Here's some crop treatment information:

I'm sorry she isn't feeling well.
May I ask what you feed your flock?
What does a normal days worth of food look like for her?
