Ihavethese tiny bugs too and have no idea what or where they are from. I have cleaned my coop top to bottom. scraped, vacuumed and shovelef. swept the actual run (i let them free range and then they come into their run, then they go to bed...we have a schedule, lol). I dusted with DE and it seemed to take care of them but, theyre back, but this time I found them in their GIANT water feeder. I didnt have it filled for them, they have 3 and this one was leaking so i left it until i could check it out. Went to check it out and lots of those flea like, gnat like, mite like bugs were in it. First i thought it was just some dirt but, it was them! I dont know what to do about them. I dont use straw except for in the winter, I use shavings in their nesting boxes now. Ive noticed the bugs no matter what I use. DE or spraying rubbing alcohol destroys them, for a short time. Sorry I cant help more...Im looking to get rid of em, too.I've also just noticed these tiny bugs!! they were crawling on my face when I finished being in the coop, yuck!! We just put the plastic around the coop for the winter. It is open on the bottom and has wheel so we pull it up close to the house for the winter. It's only a small 4 chicken coop. I haven't noticed them ever before, and my chickens free range in the fenced in back yard. I put straw I had in our little shed from last year into the coop for winter bedding. I was wondering if anyone out there could tell me if this could be where the bugs came from?? My chickens are in great health so I can't imagine these bugs have been around for long. If it is from the old straw, I could just throw that out and buy new, or buy some DE and put it all over the straw.
Any ideas or comments would be really appreciated!!! thanks everyone!
