It's hard to tell. He's still panting and sneezing, but he now sometimes drinks from the syringe voluntarily (pecking at the water drops). I tried putting a small water dish back in for him, but he fell in it, so I decided to remove it until his mobility improves. He has shown some small signs that his mobility may be improving, pressing a bit with his legs when I support him (he can't stand on his own yet but sometimes crawls) and starting to flap one of his wings, which he hasn't done in weeks. He is back to eating his regular food and a number of mealworms, but when I weighed him today he was at 120g, down from 126g last week unless one of the measurements was inaccurate.
