Is this wry neck?

Hi all, my 6 month old Easter egger hen has been unwell the past 5 or so days. At first I thought it was heat exhaustion since this is her first Arizona summer, so I brought her inside away from the flock who are all thriving. She eats and drinks but I can’t tell if she’s actually swallowing much, her crop hasn’t been full unless I syringe feed her. I’ve added electrolyte powder and nutri drench to her water.

I took her to a livestock vet a few days ago, we ran a fecal test and it’s negative for parasites. They were not much help and said to continue what I was already doing. At this time I didn’t see much of the head tilting so we didn’t even talk about the possibility of wry neck, just her wings drooped and her eyes were squinty and she was clearly sick. I also found about 6 sticktight fleas later that night attached to her top left eyelid, and one on her right side near her ear. I removed them 3 days ago but she’s still showing neuro symptoms and drops her head a lot looking down and head tilting. She is able to turn her neck the opposite way to preen her feathers but most of the time she’s turning to the right and when pecking at food she seems uncoordinated. She also stands a lot while sleeping with her head down.
Help!
