Our runty roo Penguin had that problem all the time when he was a chick. You just have to watch and keep your bird clean. They will complain and cry, but the cleaning is all for the best. I'd like to know how your pasty bird turns out as it grows. Our Penguin has been a slow learner, and if there has even been a little problem, it seems to have been with this runt, although I picked him because he was the cutest chick at the feed store!
