At this point, you're going to need something like Baytril-- this is definitely upper respiratory congestion. Likely an infection, and drugs in the water are nearly useless because they won't drink enough of it. It'll have to be injections, or using a dropper for getting the meds down. I prefer injection, it's quick, and I'm positive that it all went in-- nothing spilled. BTW-- Duramycin and other similar drugs bind to calcium (which is in their feed) and it will not be effective. Not fast enough, anyway. They would have to drink a LOT of it to make up for the initial loss in potency. You do need to separate out that bird- respiratory is usually highly contagious. I'd just get a cardboard box from the grocery and put a screen over the top with fresh newspaper and then clean chips in the bottom. Put water and feed in there and watch to see how much she is drinking. You WILL need to force water down her if she's not. I'd mix the electrolytes with just a tiny pinch of sugar to help keep up her energy and dropper it down bit by bit. Once you start medication and she is responding, THEN I'd get some probiotics to help counteract the antibiotics in the bowels. I use a powder that is meant for goats-- it comes in a big tub, and runs about $13-- but it will last forever, and it's great to have on hand. I've done this all successfully, and it works, but you have to act fast.
