seven is off labeled but i see it all the time on poultry sites. its a strong pesticide and i either use a sock to directly dust the birds or i will put it into dirt so they can bath themselves (which is what i'm about to do)

i see. Well i got so paranoid i just went to check all the chickens, they feathers look perfect all the way to the skin, which is also clean. i don't think they have anything on them. Do you think DE doesn't work? I was trying to stay away from pesticides/chemicals unless absolutely necessary.
