I am admittedly not a good candidate for a windlowless incubator, but I found a great deal on a GQF and have yet to change out the door. I have about 20 eggs in there, all shipped, and hatching upright in the tray. It is day 21 and I can hear chicks but it is killing me to see how many and how they are doing coming out of trays instead of laying down. When do I open if I cant see a darn thing. Day 22-23? Now????
