Lethargic, vomitting

[Chimichangas]

I have this hen who is around 1 year old. I found her on the floor unwilling to move and really lethargic. I gave her some water with electrolytes to see if it was dehydration, but when I picked her up she threw up a brown looking liquid that smells like poop. I’m not sure what to do.

I’ve not dealt with this but it sounds like sour crop. Here is a good place to start while you’re waiting for someone more experienced to respond:
