BJ,
I'm in a similar situation. My bottom-rung d'Anvers chicken, Jane, just hasn't been happy in the coop since we got her (3 mos ago). Last night the temp was down to 5, everybody was safe and toasty in the henhouse.. except Jane. She was perched in the run, cold and alone. She has been campaigning for house-chicken status for months (tried to follow me out of the henhouse one night into the pitch dark, freezing cold). I'm at the point with Jane that I'm thinking I'll just keep her in here until spring, and see then.
Luckily, I have two young (6wks) bantams inside anyway for that long, and a few eggs growing in the incubator. Hopefully I'll be able to make a mini-flock out of these guys with Jane. It stinks, I didn't really WANT her in the house (love her, love my other chickens.. but just don't think of my chickens as 'house' pets). But I suppose she's made up her mind. I set her up in a box last night with food and water, she hopped out and attempted to go exploring down the hallway. Actually, she doesn't seem to be upset that she doesn't have any real company except us.
Not much advice to give, since I don't even know how I'm handling this (glad my dh is patient with my chicken addiction!), but I feel your pain!
