So I washed a dirty butt this morning and, while I had her, looked for any bugs.  Didn't see anything--nothing moving, no spots or scabs or specks, no nits.  Finished the wash hours ago.  Now, reading my kindle, a tiny gray bug walks across the screen.  Kind of longer than wide, so I'm assuming it's a louse.  From the chicken?  Not a louse?  Should I treat for bugs now?  Since it must have come off of me, should I do anything other than shower and change clothes?  Possibly not related the the chicken bath at all?
