I think my chicken has either lice or mites! I picked her up yesterday and when she jumped off, I saw a little yellowish almost see through little bug on my arm which I proceeded to squish and kill (yuck!) I've sprinkled Pestene powder all over the coop/nesting area and the chickens, who was not fond of me shaking powder on them! was a ball catching them (they run fast!). What else should I be doing to get rid of the pests?
