Flitter,
Some hens of one of my dom lines have feathers that are prone to break. They are also light in color and I suspect carriers of the sex-linked slow feathering gene. Can you pluck a feather and photograph it? Do same from same location on another hen and a male dom. My bet is the bands, both light and dark are lighter on average, than in the darker hens. The rooster will provide excellent comparison for relative lengths of light and dark bands / bars.
Be prepaired for bad news of feather pecker.
