Hen puffed up and roosting alone - quiet

[JLS]

Ms. Kate is my most favorite hen ever! She was born 5/09. She's always been the top hen even though she's smaller than the rest. She rules the roost with an iron beak!

Now she's been quiet, puffed up, and roosts most of the day. She eats the corn and sunflower seeds that I throw out each morning. I have also seen her drinking. But not much activity after that. I know that my hens are molting. She has new feathers on her neck that are coming in nicely. I am unaware if she's laying. I have not seen her in the box for a long time. She's been letting the rest of the flock "run wild" lately too.

What can I do for her?

How does her crop look? No impaction? Is she egg bound? Does she have mites or worms? Other than that, it could be the molt. I know mine has been staying in the coop more than normal, because she's molting bad, feathers all over. She's the last one.

As far as I can tell there is no impaction of her crop, no mites, no worms, as for egg bound...I do not know how to tell.
