I found it much easier to mix the miconazole (monistat) into some crumbles.I've got monistat on hand for this--I'll see if I can get her to take it in pieces. Of course she is one of the most dramatic chickens in our coop (she is quite friendly but acts like I'm trying to kill her if I attempt any manhandling--and despite being ill she is STRONG). Makes crop massages and administration of meds a rollercoaster.
If you warm it a touch the crumble will soak it up.
Same goes for coconut oil.
ETA: Keeping her in a crate will also make it much easier to handle her for massage. If you have a two doored crate it's even easier.
