Well, she's really pretty, whatever breed she is.
What modifications do I need to make to be sure she's well-cared for? She seems to love the fermented chicken food I use, and I've been tossing out dried meal worms for her so she has a little more protein. She doesn't go inside the coop at night with the chickens and we live in IL, so do I need to give her a pile of leaves or something to stay warm at night?
I have a 6'x6' coop with about 18" of hiding space underneath, attached to a 6'x12'x8' (the 8' is how tall it is) entirely closed in run. There is a nice branch a few feet off the ground in the run. I saw her sleeping on the branch one night, but haven't figured out where she's spent the other nights. There is an automatic pop door (based on a daylight sensor) that leads out into our 45' diameter fenced-in garden. Maybe she's staying in the garden overnight? There are lots of great places to hunker down among the dead grasses and other plants (I didn't weed this summer). The garden is open above, and the 6' tall fence around it is chicken wire at the bottom but turns to much larger fencing that a pheasant could easily escape through about half way up. It's mostly to dissuade the deer.
I know she can leave if she wants to, but I'm hoping that the steady supply of food will keep her around. She's about as flightly as my flightier chickens, but definitely not acting like a wild pheasant.
