I have no idea what happened between last night and this morning but one of my silkies has a large bald spot on her head now. Another silkie looks like she got picked at too but not as bad. They are all doing fine and getting along now, no fighting, so I don't know what's up. They have all been fairly nice to each other, never plucking out feathers and now this.
Do chickens just sporadically pluck each others feathers out? She's not bleeding and she seems just fine, but I'm concerned.
