Yes, but my understanding is they are host specific, so they won't actually feed on you, just irritate the heck out of you. They move around so much looking for a nice tasty bird to feed on.
Now just imagine if they were biting you as well. That's how the poor chickens feel.
They are most likely mites. You can use a pine tar shampoo, but it smells funny. Just shampoo your head several times and let the shampoo stay on for awhile.
Oh yes, and dust those chickens!
