Hen losing feathers and has hunched back

[waddell5farm]

We have a hen that since a day old has always had a sort of hunched back, she has never had any issues but now she is starting to drop feathers and skin looks raw. Wondering if anyone knows what is wrong with her hunched back and what is happening with her feathers.

She looks to be egg bound, I would feed her a tums for xtra calcium.

Would egg bound be the lack of feathers or the hunch? We have noticed the hunch since she was days old, and she is over a year old now. She does not seem to be stressed, eating and drinking properly, social with the rest of the flock.
