I noticed my parrot was acting funny for a few days, hiding and being alone. He didn't eat this morning and stood at the top of the tank. I found him upside when I got home from work but his eyes were moving and he appears to be breathing. I removed him from the tank and placed him in a bucket of salt water. He looks like he is breathing but his body is bloated and he is not moving. I'd like him to pass in the most humane way. What should I do with him?
