forgot to write down the date

that I set 6 of my own mixed eggs. I guestimated and put them in the hatcher 5 days ago and still no pipps I must have mis calculated ugg.... I will never make that mistake again! When I candled them before putting them in the hatcher they were doing well, but now I dont want to open hatcher to check if they are still ok. I guess if and when they hatch it will be a surprise. I now have a big calander hanging over my bator.
