Ok, I have read in several places, do not wash your hatching eggs, you could push the bacteria inside the egg and kill the chick. You also risk the chance of removing the film on the egg that protects the chick. I have also heard others who disinfect their eggs before they incubate. And I have read that the best way to clean a hatching egg, if you must use that egg, is to use a light sand paper. Well, it has been snowing here and the eggs look real bad, splashed messy. I am learning to use the Bator right now, so I do not want to pitch these eggs. Just not interested in infecting the bator. Just what do you use to clean a hatching egg you want to use? What Chemical, if any? What temperature water, if any? Have you cleaned eggs for your own hatch? How did it turn out?
