Fuzz coming off around vent area

[gkeesling]

I have a 9 month old Plymouth Barr Rock hen that seems to have some of her fuzz coming out around her vent area below the feathers. There is a strip about 2 inches that has come out and she looks naked there. Any one have any idea as to what could be causing that? She looks and acts ok otherwise.
