desertgirl, it can take a while, just stay on top of it. Have you tried the molasses in the water thing? It cleared our pasties fast.
purplepeep, yes, often they will peck at their bum after cleaning, especially if you pulled some fuzz off in the process. As long as they aren't bloodying themselves they should be fine.
I will reiterate "Adding a small amount of molasses to the water will help pasty chicks recover quicker. Mix it so the water looks like a weak tea." It worked very well for ours after being suggested to us by another BYCer
