1 yr old laying buff Orpington - suddenly not walking - seeming loss of wing control . Need help steps forward!

Tucson , Arizona . Yesterday I found my over a year old buff on the floor of chicken coop not able to walk. Picked her up and brought her inside. She is alert, was interested in yogurt and food , plus water, but not able to walk and when I pick her up her wings kind of fall out to side . On floor she kind of flops to side. She expelled a couple disgusting green, diarrhea poops yesterday and a more solid stinky one today. Seems to be eating less and water but still alert. Have been giving her poultry cell, nutridrench poultry , strike and fresh water / food. She laid an egg this morning too.
Two weeks ago I lost my oldest hen - she was spitting up fluids and eventually really didn’t move much. I had another sick Easter egger who I brought in and treated and she’s fine. She had a dirty vent with white discharge. I treated the entire flock with Corid.
Not sure next steps …. I was hoping she’d be up and walking now.
My flock is 20+ chickens, 5 turkeys and goats. They free range during the day and are locked up in a safe run/coop at night. She usually roosts within the run.

That last poop pic looks pretty bad. Usually black like that from blood somewhere in the digestive tract. My best guess since it came on suddenly would be that she found something bad in the yard (like old nails or bits of plastic), ate it, and can't pass it. Depending on where it's stuck I think it could press on nerves causing her discomfort and strange stance. If a vet is an option that is where I'd take her. Otherwise I'd keep her separated with plenty of food and water and hope she can recover on her own.
