Hen throwing up - Help

[shareverwonder]

My 3 year old hen has been acting very lethargic and has been throwing up what appears to be clear drool. Not sure what to do with her, she just stands around. I have her separated from the rest of the flock. Please help!

Is she eating at all? Drinking?
Could her crop be blocked? If you feel around her neck you may be able to feel a blockage, which could be attributing to the drool. If nothing can go down it only has one option!
Just one idea.

I haven't seen her eat or drink anything that I can remember. You never pay much attention until one is sick. I will have to check her crop when I get home from work.
