I stopped the ACV as soon as I noticed the problem. I've been sticking with plain water since she's getting poly-vi-sol and I don't want too many variables to account for. Our bathroom is so tiny and damp it's like an indoor outhouse. Right now she's in my lap. The only symptom that's still apparent is the closed eyes. She just hopped out of that carrier about an hour ago looking spry. She is opening her eyes all the way, but not as often as I'd like. Her eyelids are pale again. I think it's because she's squeezing them shut. Again it could be sleep deprivation, but I think her eyes are becoming more red. It's normal for these birds and I've been expecting it, but photosensitivity would be a surprise.
O.k., now I think she's having me on! Every time I look into her open eyes, she shuts them. I'm not that ugly!
