One of my Delaware hens is really getting picked when she roosts. I went out tonight to observe. There is one hen (likely a Del/Rock cross) that is the most picky, but the hen that is getting picked at is also really picky. She kept grabbing my jacket and shaking it, and behaving in ways to incite the other hens to pick at her. I'm not sure what to do when she is driving the other hens to peck at her. Would this be related to molting somehow or I wondered if she might be mite-y? I could dust with DE tomorrow - maybe they need a sand bin to dust bathe in?? I have Eprinex ordered, and assume it will kill any remaining mites? Any ideas for me?
