I'm sorry about your Quail.
Did you put any ointment into the eye or just clean out the pus?
Apply a warm saline compress to the eye, clean out any pus, then put ointment into the eye. Original Neosporin is fine to use if you don't have Terramycin eye ointment.
Since the hawk hit and her too, she may have also flushed and hit her head. Hard to know.
Quail are quite fragile and is she bonked her head, she may have a hard time recovering.
I'd give the sugar water if that's what you have, but I'd also begin giving vitamin therapy as soon as possible. 400IU Vitamin E along with 1/4 tablet B-Complex.
Can she stand and walk at all?
