Trying to diagnose swollen left eye and possibly ear.

[johnnyohio]

Only the left side is affected. It is swollen and she seems to be off balance on the left. There are 4 other birds and they appear o.k.
For lack of anything better to do, I was going to treat it with Vet Rx but I am not confident that I know what the problem is or that I am doing the right thing. She is lethargic but will eat some food if I put it in front of her or hold it for her.

Any help will be appreciated.

Have you looked closely inside her ear? I would suspect an ear infection with the off balance and swelling only on that one side.
