i know a lot has been written on this already, but I haven't found an exact answer to this yet--- We placed the eggs in my sons incubate today, in the carton. he marked one end of each with a pencil to tell "which end is up". He is planning on just flipping them over 3 times a day (there are only 7). Will this work? I've read a lot about tipping the carton, but he really wants to do it himself. will it still work! wow, lots to know!!!!
