That looks neurological. It might be Marek's disease.

10 days have passed. I'm stopping with the antibiotics. She still has good appetite. Eats and drinks normally, good weight. Same symptoms. Nothing has changed. The other chickens in the coop are egg farm rescues, so I'm sure they are vaccinated. Maybe it is time to return this one to the coop and see what happens. Better to die in the coop than dying alone in the cage.

I wouldn't be so sure about returning the hen to the flock because Marek's is contagious. But then again, it could be something else.

If she has not improved in 10days (still acts like she does in the video), it would be kinder to put her out of her misery than to put her back into the coop. She has been separated for a good while, she will most likely not be accepted by flock (viewed as a stranger) and will be picked on. In her condition, she is not able to defend herself from attack and will most likely not be able to eat/drink properly, even if she is allowed access to food and water by the others.

@AmazingRachel makes a good point - if this is Marek's, it's contagious. Now, she has been housed with the other birds, so likely they have all been exposed. But--a bird that is symptomatic sheds the virus more heavily so there's a greater possibility of spreading the virus.

Thanks for the comments. I will see how they behave together. The others are vaccinated. I can always isolate her again. I'm still giving her vitamin E, sunflower and pumpkin seeds everyday. I will keep reading to see if it could be something else or try something else that I haven't tried.
