Hi, sorry if this is in the wrong place (struggled to choose between here or the predators and pest section) My chickens have become completely infested with tiny, dark coloured, pin prick size crawling insects. I have no idea what they are, whether mites or lice. They're swarming everywhere, are in the grass near the chickens, you can't go out there without getting infested yourself. They're all over us humans too!! I've read all the info I can find on here, but have no idea where to start. Does anyone have any experience like mine? Know what the bugs likely are? It's a nightmare and my poor chickens are scratching away.
