I was just thinking that this morning! Looking at how absolutely perfect the ladies that are coming out of molt look ,still have one that's a work in progress like your girl but they'll get there. 

Yes, we just assumed there were some sort of internal issues with Winnie -- who knows. I feel bad because she was my cuddly chicken -- always jumping up in my lap. At least she died quietly and I got to comfort her a bit.
This is my first experience with molting -- it's really something! It's amazing how beautiful they look again when the new feathers come in, though!
