I hatched this baby out, and unfortunately she was the only one to survive from the clutch, so I had to go to the feed store to buy her two buddies so she wasn't lonely. For the past few days I've been giving her a mix of sugar water with electrolytes, medicated feed and egg yolk. After feeding she always seemed a bit perkier, until this morning - she seemed to take a turn for the worse. The odd thing is, I almost feel like whatever she has is starting to affect her neurological system, because she will turn in tight little circles every now and then, like she's dizzy.
I actually did give her 1/10cc of Tylan 50, as I've been reading that sometimes (a long stretch, but stranger things have happened) that can help treat aspiration pneumonia. After giving it to her via dipping the tip of her beak in a teaspoon with the medication, she seemed to stumble about a bit, and still gasping

I should note that she is still peeping quite often, and I can't hear crackling when I listen to her breath, but I do hear a 'click' sound every time she breaths.
I've dealt with and treated cocci many times, and Corid has always been a reliable medication for our chickies, but I've never dealt with a chick like this. It breaks my heart to see her like this, and I just wish I could find a solution to save her, but I fear it is too late.
