There was a water spill in the coop yesterday and I was moving away the dry bedding so I could remove the wet bedding. As I was moving away the wet shavings I saw several of these little bugs. They look much larger than the red mite pictures I've seen. And they aren't really red, but more brown football shaped. I've looked the chickens over their vents and feathers look to be in great shape. They may just be normal little critters but if not I'm hoping somebody can tell me what they are. They are small but pretty visible. They didn't seem to be hiding in any cracks but just in the bedding. In the first photo it's on my finger, the next two it's actually stuck on it's back. And the last one is the best picture I could get of it crawling. Any ideas?
