Hi all, absolute chicken newbie here. Very grateful for the resource. I have a small flock of 7 pullets, and one of my Rhodebars seems to have some issues with losing feathers and a skin irritation. She is smaller than the rest and I'm not sure if this is self-inflicted irritation, if the others are pecking at her, or if it's some other type of malady. Here are a couple pics--any feedback greatly appreciated!
