Suzie is doing a lot better to day. she looked around when I checked on her, wasn't puffed up and, I held some food out to her and she ate some.
It's good she ate. Try ensure she is drinking too.
Is there any way you can get photo's? It's very difficult to go by description only as we all see and say things differently.
Did you manage to check her crop? This is important. So no feed or water overnight, then check first thing in morning for an empty crop.
You said she is pooping, can you describe her poop please?
The Poofy face is concerning, but without a photo it's impossible to see what you are talking about. Is is swollen? Which part exactly?
When (if) was the last time your chickens were wormed and what were they wormed with?
Have you checked closely for lice/mites?
Did you give her some Nutridrench or equivalent as suggested by ChickenNanny13?
Can you check for an egg - lube up a finger (vaseline or any oil) and gently insert straight into vent for 1 to 2 inches to feel for an egg. If no egg, it will just feel soft.
While you are at this check her abdomen for swelling. Cup your hand from behind her between her legs and back towards her vent. What does that feel like? Compare to others if that helps.
