Chickens head shaking,really drowsy

[Wyorp Rock]

She was weeping and sneezing and just lazy would not move. Now she won't move anymore and she is a little bit of balance she is not wheezing g anymore and I will try to get a pick of her poop

I would treat her for the lice/mites right away. Today if possible. Treat her, the others and your housing.
Get her hydrated first, then see if she will eat.
