I've got my 'bator all set up and ready for the eggs that are being shipped to me. How well does the egg carton method work? I've read bits and pieces, and from what I'm putting together, you put the eggs in small end down, and prop one side of the carton up at a time instead of turning right? How high do you prop it ( how high a board, etc do you put one side on?) Do you place it under the short end ( 2 egg side) or long side ( 6 egg side of carton)? Anything else?
