SICK CHICKEN HELP!!!!!!

[Lilchiknmama87]

Have a hen just under a year she is a golden lace. Was going out to shut the coop the other night (3 days ago) and noticed that she was laying on the ground level which is rare at night they usually sleep on top together (have 3 chickens total). Let her be that night and figured it was nothing. Since then she has stayed in basically the same spot on that first level and is unable to stand up. It appears she is laying down with her legs kicked out the side. One leg is fully extended out (she rarely moves this leg but can move it) and the other leg goes from being under her to kicked out next to the other leg. Also I have noticed that one of the claws is often shriveled up sometimes. Other then the fact she has not stood in 3 days, and the strange positioning of her legs (does not appear to be the common leg positioning of Mareks disease) she seems fine. Not eating as much but will drink water if left near her. We have been putting some electrolytes in her water. She will roll around on that bottom level but never stands. Wanted to see if anyone had any ideas on what could be going on. I have a medical background and to me it almost seems like the human version of a stroke as she has one leg in full extension and weakness in the shriveled up claw. Any and all help is appreciated to try and get this hen back to normal. Let me know if have any questions. Thanks in advance

This sounds kind of similar to what I have going on with one of my pullets and I cannot figure out what's is wrong with her.
