question about using DE in the run area

[lorain's fids]

I just put down sand mixed with some pea gravel in the new run area. Now before I let the girls in there should I mix some of the food grade de into the sand. And if so about how much. The total run is 6x12, but I only put sand/pea gravel in a 6x6 area which is the part with the roof. Should the grass/dirt also be dusted with DE or just the sand area?
I am learning as the girls are growing- 8 weeks old this week.

I think you will be fine putting it down with the sand, ( How much) just a hand full here and there.

I agree, a couple of handfuls in with the sand and gravel. If you have a special tub for dust bathing it is good to put it in there too.
