One of my EEs in a flock of 4 (2 EE, 2 Barred Rock) perpetually has a couple of small feathers sticking up on her back between her wings. She's definitely the lowest in the pecking order by her behavior around treats, etc. Should I assume she's getting pecked? There isn't a bare spot (yet). Can feathers just stick up like that naturally? (Sorry....newbie question).
