The ear infection is a possibility so you might want to find an appropriate antibiotic but considering her crop you may want to hold off for a day or two? I don't know. Anyway, you can still put a drop or two of Poly Vi Sol in the veggie broth and water (I'd use a splash of gatorade). Use a dropper but also leave the water mixture (and veggie broth) for her to drink any time. Empty her crop by tipping her forward and massaging the crop. If a bunch of liquid comes out you know it's not doing her any good in there. I've heard of someone here who has actually used something for yeast infections in women but it has to have the right chemical ingredient (starts with an 'N' I believe). You might look into that as a plan 'B'. Has she been wormed in the past?
