If she has not had an adult moult already I would say she looks to be starting an early one. If those feathers are the ones she has had for all that time they are maybe just giving up the ghost and she is needing new ones.
I had a hen last year that looked terrible ~
She was hatched in May 2014 so didn't have an adult moult that year and by the time we got into summer 2015 she was looking ratty. In the autum all that shabby stuff came out and she grew a new set of feathers by Christmas ~
