Coccidiosis help please!

You could try giving her medicated fluids often with a syringe down into her crop or tube feeding. Here are some links about giving small amounts of fluids down into the crop:

Thank you all for your help! We did a 7 day full dose and 5 day half dose of the corid since the case seemed severe and while it took close to the full dosing for some to improve, they are all on the mend. The bird that got the sickest is still laying less frequently but appears in good health. I appreciate everyone’s support!
