Chicken with respiratory sickness?

[The Chick Addict]

Is she pooping?

Yes she is, she's doing large, watery poops with some urates and green specks, they look like this:

I'd check her crop in the morning to see if its emptied. The liquid may be due to a crop problem which is not uncommon in hens that have reproductive disorders.

Okay, I'll do that tomorrow morning! Just felt it and it feels soft but not completely empty. Uh oh, how would I know if it's a reproductive issue? I just felt her abdomen and it's still slightly swollen though I drained all of the fluid... could that be an indicator? It doesn't feel hard at all, very soft.
The poor girl still isn't looking great and is pretty lethargic.
