my sister stepped on my parakeet while he was walking around. he keeps moving in circles, i think he's blind in one eye because one eye is all red. He's eating but at the same time he goes in a circle, it looks like hes trying to see through one eye. Is there anything i can do? before he would twitch his neck/head. Right now hes sleeping. Should i put him to sleep or should i just wait it out? I can't afford a vet right now the closest one is almost 2 hours away.
