they are on day 11 and all are fertile and growing. The humidity is at 40%. I haven't misted. How do you do that? Just spray them with water?
Yep... or pat a wet sponge across them... it depends on how the air cells look... are they the right size for day 11? If the air cells are the right size, don't mist or sponge... if the air cells are too small, then mist or sponge once a day... it will make the humidity spike for a while, but the evaporation of the water off the shells will pull more moisture out of the eggs...
