Trying to get him to take it now. Its been a whole hour of trying and he still won't take it. We can get him restrained perfectly in a towel, but he refuses to open his beak. If we force his beak open, he flails his tongue.
He has incredible spirit- but it's misdirected right now.

Edit:
Ok, I've got it. I've had to do that before with other birds, but none of them have ever fought this much. Poor baby!
There aren't any local avian vets in the area anymore
but I'm going to go to a non-avian vet who has some experience with birds tomorrow and ask her to run a fecal gram stain, and to especially look for a collection of gram-positive rods. I don't suspect she'll be too thrilled with the idea, but AFAIK the process doesn't really differ from a mammalian gram stain.
