Corid drench instructions linked below. You still want the water to be mixed Corid too.Nutridrench contains thiamine mononitrate(b1) in the ingredients list, so I wouldn't use that while treating for coccidiosis. I would use the molasses flush that @Wyorp Rock recommended. Have you started the corid treatment yet? You may want to drench dose her, instead of mixing it in with the water, like you do with the rest of the flock. That way, you know she's getting enough. I use the corid powder, so I don't know liquid drench dose off the top of my head. I'll see if I can find it in my bookmarks. I just lost my rooster and one hen from a coccidiosis outbreak, so I had a few pages saved for quick reference.
The drench is just to get a "jumpstart" but all fluids the bird consumes should be the mixed Corid for the full 5-7 days.
