It's day 19 and I just put in a wet cloth into the incubator for humidity. Already one has broken a small piece of shell off.. nothing drastic but it is very exciting!! The temperature is about 101 degrees, and it's a still air incubator. Humidity is a bit over 50 before I added the cloth, probably more now though. Is this good? This is our first hatch and I am really hoping it will go well.  I have a question, all of the eggs are clustered together right now-- also, there is nothing on the bottom of the incubator (I've heard that people use egg cartons?) should I move the eggs apart, and/or add something beneath them? Not sure if I should do anything.
