Millie's tail feathers are gone...

[mudhen]

I've done a search for any thread on this subject, but no luck.
Over the past week, Millie has lost all of her tail feathers.
Everything seems normal, she eats, struts, poops and is a bright eyed as always.
No one is fighting with nor picking at her.
Any thoughts?
Here's a photo of yer yesterday (in the center behind the stick). She had just settled down for a nap and you can see there's no more tail feathers.

I live on a ranch in Az. north area, I was reading every one blogs or jernals I've got a chicken book

with me now and I looked up Molting which is when a chicken will lose there feathers and do this a couple of times a year. I had a little Silkie who was always Molting she looked so rattie but you gotta love them. Just a idea.

I don't think its a result of molting. Its only her tail feathers.
