Okay, so I did some research and I'm pretty sure it's not wet fowl pox. She doesn't have any lesions anywhere, just the swelling. Which, has gone down some since last night. So, that's encouraging.
Since the swelling has gone down, I didn't try to drain it with a needle. Just did the same kind of massage like I had done on the other side before it had hardened. Quite a bit of goo came out of her eye. I put some of the Terramycin on her eye, not because I think the ointment will help at this point, but because I thought it might help it not get glued shut. I figure it's like the wound...if it can stay open, it can drain.
As far as why I don't take her to the vet...originally, it was because I really couldn't afford it. Now, it just seems like it would be a waste of money. There's not much they could do that I'm not already doing. She is improving, albeit slowly. Even the new swelling has already begun to improve. This site has been a wealth of information (particularly ThreeHorses) and I feel that things are under control. I know that if I have any questions, I can come back here, ask, and get a good answer.
Anyway, tonight's update: I already mentioned the swelling has gone down. She hasn't been able to roost since yesterday evening. She keeps falling off. I figure all the swelling has really messed with her balance. Probably affecting her inner ear as well.
I'm still syringe feeding and watering. Now that she can't close her beak again, I've seen no evidence of her drinking on her own. I can close her beak with my fingers (which I couldn't do last night), so I'm optimistic that once the swelling goes down more, she'll go back to trying to drink on her own.
I've gotten a good look at her left eye. It looks pretty good. Although, she still keeps it closed most of the time, she is opening it here and there and definitely reacting to the light on that side. So, even if her vision is gone in the other eye, I think she can still have a good quality of life.
I'm really tired, so I think I'll go to bed. Will update again tomorrow. Bye for now!
