I just spoke with my vet and she said that chickens don't normally run fevers and that normal a normal rectal temp is 105-107 degrees. That said, I would keep her in the house and keep her warm.I picked up a thermometer and her temperature was 105.5 Degrees F. She just turns away from me whenever I try to get her to take food or water. She isn't sitting or laying down she is just standing. If I take live mealworms she will turn away until she notices them moving around then she will eat those. So far that is all I have been able to get her to eat. I have only given her a couple. I dried her with a towel after the bath and have kept her in the house. I will probably keep her inside for tonight at least. Since she doesn't have an elevated temperature and I have not noticed a foul odor from her I am going to hold off on the antibiotics for now. I will have to wait until my wife gets home so one can hold her and the other can see what the inside of her beak looks like.
The chicken that we had die had problems laying since last winter, soft/rubbery eggs, weak shells, a long time between eggs. She had no symptoms, wasn't lethargic or anything. She was running around playing the day before then I found her dead in the coop the next morning. So if it is something contagious it seems that the symptoms are different. I have separated her just to be on the safe side.
She seems far more alert than she was this morning but still not moving much, no eating or drinking, and no droppings. She is at least opening her eyes and moving her head occasionally now.
