i set up my egg tub with just vermiculite, but after 2 weeks i decided to put in a piece of the white light diffuser stuff to keep the eggs up and off of the vermiculite. they looked ok before but now they look perfect. the only problem is when i pull the egg tub out of the incubator to check on the eggs and open the tub to let air in, i have to be very carefull or the eggs will roll back and forth and hit each other and the sides of the tub.

Has anyone had this problem?
Did you fix it in someway?
Do i even need to open the tub every couple days to let fresh air in?
