I and many others use a carton (see the one they came in) to incubate and hatch in. I trimmed the extra edge off of the clear, 10 egg, carton down as much as possible, and removed the top portion that folded over. This left me with bottoms only, trimmed so they could be set side by side. They need to fit close together. I did this to 5 cartons. I then used a exacto knife and made a cardboard box that fit these five trays perfectly. The sides are about 3\\4" high. A desk stapler helps here... I then used clear packing tape to connect all the trays together and to the cardboard box I had just made. Now you have a 50 egg, custom tray that can be propped up at about 35 to 45 deg angle. (prop up the long side) When you need to turn your eggs, just turn the whole try end for end, 180 degs and you eggs are now turned 70 to 90 degs. Its quick, your in out in no time... When its time to lock down, set your try flat and leave the eggs alone. You will find you get better hatch rates with eggs standing on end at hatch time. Good luck Bill
