Mites on broody

[endrit]

One of my broody hens(day 18) is being infested with mites, My question is,is it safe to use dust permethin on my hen,is it safe to use it around her eggs(and or on the eggs).
my hens have never had this much problem with mites this is the first one and caught me off guard. im worried that the dust will make the eggs unable to hatch.

I have never used permethin dust. I use Sevin 5 on broody hens, nest, and their eggs; sometimes on the chicks.
