My RR seems to have some molting feathers on the back of her neck and between her wings. This must have happened yesterday or last night. I have checked her for bugs and gave her a warm bath and have not noticed and bugs. She's acting normal. She comes when we call her and allows us to hold her and check her injury. I have not the slightest clue what could have caused this and if we need to separate her from the flock. I heard that they may get picked on by the others chickens.
