DE is irrelevant in my opinion and completely ineffective in MY area with high humidity. My friends husband a mile or so down the road insists on using it yet they had to treat when I picked up one of their birds and clearly showed them egg sacks on the feather shafts. We have very mild temperatures and lice thrive in winter here.
But I do actually agree with the others who posted after me... in that I have seen the same thing with other birds grooming them especially when I used to ferment my feed, just forgot that possibility. But her skin does not look red and irritated as it might if the issue were parasites.
