you get a tub around 6qt in size. put water in the bottom, go to home depot and get the light grid that has small squares, used for drop ceilings. cut to fit tub, some breeders stack them to keep eggs out of the water, others will use something like pvc to get the grid out of the water. now your eggs will remain dry and instead of putting the lid on use glad press n seal. nothing else like saran wrap. use press n seal. this will keep the humidity up. when you check your eggs about once a week, this will give them fresh air. about the last 2 weeks, peel a corner back to make a very small hole . this is when the eggs need a lot of oxygen. also when checking the eggs be careful not to splash them or have them roll. when the hatchlings pip, replace the press n seal with the lid that you put a few air holes in so the hatchlings don't get out.
