OK so I am using peralite for my incubation substrate in a hovabator (cause I was not able to build an incubator in time.

I currently have about an inch and a half deep of substrate in my container with egg grate inbetwwen the substrate and the eggs.

my temps are between 88*-90* and my humidity is between 88%-90%.

For some reason some of my eggs are shriviling up????? What causes them to do this??? Not enough water/humidity???

If is switch to vermiculite can I just put the eggs into the subsrated or do I need to seperate them like I do with the peralite???
