I have tiny bugs in the coop on the beams and stuff. I think they are mites or lice. I have seen a few tiny bugs on the chickens. The feed store recommended louse powder because that is was what the poultry farms use. How long do you have to wait until it is safe to eat the eggs? Luckily my chickens are broody or too young right now. How do you get the powder to stick on the walls and roof? I want to try DE but the brands that are around do not say it is food safe on the label. Is there are brand that is safe to use? Any ideas are helpful.
