Most of the folks on here suggest using the yeast infection medicine you would buy at a pharmacy. It may sound odd, but that is your best bet. There is a description in this article.

I would take the round suppositories, peel off the coating and then cut it into pieces to feed to my hen. There is a wax in it, but I decided I would rather feed her that than the strange stuff in the cream.
The stool softener (sodium docusate) should help her to just clear out whatever is left in there. I would do that and the coconut oil treatment at the same time.
Let me know how that sounds. I know that there are herbs that can work for yeast. They will take longer, and you will have to make sure that they are not toxic to chickens. Most folks on here just use conventional stuff, I am guessing for those reasons.
