I wouldn't have worried about the Neutrolin B either, not a big deal...Like I said before, if since you had to actually compound both the Antibiotic and the Anti-Fungal, the vital meds for her, and because they were compounded you'r only giving her literally 1-2 drops, if she were to ever spit-out or sneeze-out the entire dose of either the Antibiotic or Anti-Fungal, I would definitely re-dose her with them...
What you need to keep in-mind is that when we're talking about an Antibiotic or an Anti-Fungal medication, and we're talking about literally "1 or 2 drops", there is not any chance of "overdosing" her...Actually, "overdose" is not the correct term to use with Antibiotics or Anti-Fungals anyway, but rather "over-medicating". There is absolutely no negative effect that is going to happen from giving her another drop or two of any of the medications you have, and since it's so vital that she get the full-dose of both the Antibiotic and the Anti-Fungal each and every day, if you see her definitely spit-out or sneeze-out the entire dose of either of them, then you almost HAVE to give her another drop of it just to make sure...There are no negative effects from doing this with either of those medications in the quantity of 1 or 2 drops. Even if the dose of either of those two meds was a full teaspoon, and let's say you accidentally gave her the antibiotic or anti-fungal medication twice by accident, so you gave her 2 full teaspoons instead of 1 (or even tablespoons for that matter), at worst it might upset her stomach or cause her to have a little diarrhea. Now you NEVER want to do this with any type of Narcotic pain medications, anti-anxiety drugs such as Xanax, Valium, Ativan, etc., or any anti-inflammatory drugs such as Metacam, these are the drugs that she could "overdose"
on...but if you see her spit-out the entire drop of antibiotic or anti-fungal, then yes, go ahead and give her another drop of it so you can ensure that she gets it.
How is she doing now? Is she eating normally? Sometimes when they are on multiple medications they can lose their appetites, hopefully the daily dose of Probiotics will keep her stomach and GI Tract settled and keep her appetite up...Are her Respiratory symptoms going away? How about the conjunctivitis in her eyes? I'm hoping that you're seeing the actual signs/symptoms of the Psittacosis Chlamydia starting to go away, specifically any of the Respiratory issues...
****As far as the medication/liquid coming out of her nostrils, bird's sinuses are exactly like ours in the sense that their throats, nostrils, eyes, and ears are all connected by the sinus passages. So birds can also have something they drink "come out of their noses", lol...What you do need to worry about is if it only came out of one nostril but not the other, or if you notice her breathing through her mouth (open-mouth breathing) instead of her nostrils, because that's a sign that one of her nostrils may be blocked with something; with Psittacosis they can really get a lot of congestion/pus/liquid in their sinus passages, so it's quite possible that one or both nasal passages may become blocked...Also, sometimes birds can develop growths inside of their nasal passages that block-off one side, and this usually results in them open-mouth breathing among othr symptoms, like watery eyes...usually these "growths" are just benign Polyps and not life-threatening, but they typically do try to shrink them with steroids or even surgically remove them.... I don't remember if they did an X-Ray on your bird, did they???? The reason I'm asking is because when they x-ray a bird they x-ray their entire body at one time, and they would have seen any growth/blockage of her nasal passages on the x-ray for sure...
