Hen sitting down, but not egg bound

[Mei&Popcorn]

Hi, my hen has been sitting down a lot, and she's been kind of crouched down with her tail held low. However, she isn't egg bound because there is no egg. There appears to be a "fullness" lower down from the vent... any idea what it is? I gave her a warm bath to open up her vent if she needs to pass it, but other than that, I don't know what to do. Thanks.

Is she sitting on eggs in the nesting bow or outside sitting down?

Just outside sitting down, usually every couple steps or so. She seems to have perked up now, though

Hi,
What happened to your girl. I have a hen doing the same thing. Walks a bit and sits down.
