My kids have been around the chickens this week, and we have found little brown bugs crawling on the eggs in the nests. I have assumed were mites. Very tiny. Last night and today I have found a couple little bugs similar in size, but light green or white in color crawling on my cloth desk chair, and myself. They do not bite like a flea, just itch when they crawl. Aren't lice bigger? I've never had lice, or the kids, so I don't know which they are. Now, what do I spray or dust the coop with? and will regular human lice shampoo get rid of these things in the house? Thanks for any help.
