I really hope it doesn't become "a thing", and that somebody doesn't decide to make a breed out of something like this and make chickens even more visually impaired than the current mutants... Silkies, Polish and the rest of them weren't supposed to have feathers like that either (or all the feather-footed breeds for that matter) but here we are. You may need to trim that as the chick gets older and more feathered out, if it starts to get in the way of its vision.
