Today I processed 2 birds. The first one I didn't see any bugs on him, but the second one had lots of these tiny red bugs on his legs. I checked a couple of my other chickens and a few have the same thing on their legs and butts. No one is acting sickly and everyone looks healthy otherwise. What are these and how do I get rid of them? I ended up skinning the second roo because it creeped me out.
