Hi. Cleaning out my wooden coop and found quite a few of these. Any ideas what they are?? The video is zoomed right it to try and see the bodies. Can't upload video so done a screen shot. They are so so small to see. They looked like black dots.

Could be mites.
It's hard to see, the picture is quite blurry.

Mites are spiders or arachnids, and have 8 legs. The picture looks a lot like red or roost mites.
My old eyes cross from trying to look at your picture.
