I dated the first egg I set in the incubator, along with several others, but did not write it on the calendar. Now, I have this dilema... I appearently rubbed off the dates when rotating them! This will be my second hatch so I am not an old pro yet. What is the best advice. I have a date written down about how many of who's eggs were in the bator on the 28th of Dec. but, for the life of me I can not recall the date I set them. If I carefully check them for pips every day, and there are none, can I rotate a 1/4 turn? I can tell which ones are the furthest along. Thanks for your help.
