My hen is all baldy -- What would be causing this?

She's got a smooth baldy man head now LOL and no one has drawn blood so thats why I thought, hmm, no picking. She also doesn't get picked on when I'm out there.

Maybe she is just going to be a bald chicken. Perhaps the feathers got pulled out and just aren't growing back or something.

Strange huh? ... She's been like this for a while now, when I first noticed I dusted them, cleaned the coop, dusted all the hens, run, etc and checked them over for moving dandruff (mites) and lice. No mites, and no lice as far as I can tell. They've been dusted on a regular basis and their coop gets dusted everytime it's cleaned.

Oh yeah, and I would have dusted with Sevin dust but it's banned under the pesticide ban here in Canada unfortunately and really the only thing available to me is DE these days.
