Chickens don't know if they are protein deficient. They don't stand around the hen yard saying,
"Man, we gotta get some more protein. Hold still - Im gonna pick your feathers!..."
One of the problems I see is that people expect that chickens adhere to our way of thinking. We go so far as to imbue them with human attributes in our zeal to have them be "more like us." So we observe and dissect what WE do and see, without genuine scientific analysis, and come up with the conclusion that our chickens are protein deficient. Since that is the case in our minds, we look for ways to tie their behavior in with that.
But they don't know anything about nutrition... I've never seen a chicken studying any of my poultry books.
They just do stuff according to their nature.
It is accepted among poultry experts that feather picking is due to two factors:
1. The feathers are there -
2. The birds are close to one another.
It is typically considered a problem found in crowded conditions. It isn't exclusive to that, however. It can become habit during the winter when they cannot get out, or as a result of pecking order squabbling, for example. Then later, as when you are "free ranging" them, it is imbedded and continues.
But it is generally thought to be a symptom of overcrowding on some level and can be a precursor to other problems.
