Broody Hen, I think?

Yes, except she is more like this

Dang that thing's possessed!

I gave up on the cage and let her out. It’s been very cold here and I felt awful having her sit on that cold metal. She isn’t staying in the nest all day as she once was. She is getting out a lot now and free ranges with the others. So hopefully she will continue getting over it.

UPDATE: She is STILL broody. The others boot her out if she is in their favorite nesting box and she makes whichever box she can get in, her home. She has come out once on her own in the last week that we know of. We are getting her out at least twice a day and she eats/does her business and goes right back.
She appears otherwise healthy, good color, plenty of energy it seems. No mites. I just wish she would get over this!
