When I`m hatching, I generally take them out once a day.  If they`re too wet or too weak(too new)  they stay in til the next morning.  If they`re still somewhat wet, but really active, I`ll go ahead and take them out.  Just what works for me.  I find the humidity usually-bounces right back up there, or I throw in a wet paper towel to give it a boost, but I only have to do that if there are`nt many chicks.
