Thanks so much for the link! I was seriously thinking of isolating her. Everything I read about isolating always takes place in the summer. How do I isolate, still maintain good winter feathers, and not have her get too cold without flockmates to keep her warm at night? I guess I could find a thread here that might answer that, lol. I thought of having her outside in a crate in the run during the day and then bring her into the basement where it's cool but not cold at night. Sort of semi isolation. That way she'd keep contact with everyone so if she did lose some winterization, she could always cuddle up at night with the others when she comes out of isolation.
