A combination of peat moss, dirt, and wood ash is very good. I see no reason to exclude DE from the mix, you just don't want it to be the main ingredient.
I assume your humidity is too high causing the chick to either have too little room in the egg to swing its head and chip out or drown in excess fluid. Do some of them have their beak sticking out of the shell? That is a good indication. The better humidity control will help but you will...
