Oh gosh, I didn't realize that this had been posted in here. I got so tied up with other things, that I forgot to check back.
Thank-you everyone that was interested in helping. You really are a good group of people!
I've managed to get help from a family member to take Parker to the vet. At least within a certain amount. We've had a bit of a rough start, seeing as I had the vet bills from Quinn, the and cost of buying everything to bring them home (all in one month).
We couldn't get an appointment until Monday, but Parker is doing okay. She hasn't passed any more undigested seeds since yesterday, although her droppings still aren't right. I've been giving her Nystatin (or at least trying - I still lack bird holding skills) and feeding her ground up harrisons pellets. She seems to be eating some seeds, but it's hard to tell if she's just shelling them and tossing them.
It is the Amphotericin B that she's been given. They want to follow up in about 2 weeks to see how things are going.
I've sanitized everything with F10 SC, and have been keeping her in the bedroom with the heater running since we just had a big snowstorm and cold snap hit here. Unfortunately Parker is a bit under weight, and her appetite isn't great. Up until now she wasn't vomiting, but I question if the mushy whitish blob I found in the bottom of her cage is in fact that. And to top all things off, two nights ago she seemed to have suffered her first night fright - 3am in the morning flew blindly into the cage sides (and everything inside). I was able to calm her down enough that she crawled up the bars and back on to the perch. Poor baby.
Still not 100% sure how this happened, but either way, I'll let everyone know how she's doing. Just have to see how things go day by day.
Iím really sorry youíre having these problems with Parker. Poor little girl. One thing that helps a lot with night frights is to get one of those little plug in night lights and have that plugged in next to her cage at night. Cover her cage except for a small section and make sure the night light is shining into the cage (the little wall night lights arenít too bright so it wonít keep her awake). A nightlight makes night frights less likely and if Parker does have one, she can at least see.
