I don't mind that you're not YHF, either.
There would be much to consider before settling on this as fact. We'd have to come to understand how loose feathering is related to what other traits and then how those traits actually come to affect laying. Anecdotally, perhaps, it's safe to say to that most of the breeds traditionally prized for laying are at least "fairly close feathered".
Yet here is an opportunity for yet another SOP, food for thought moment. Turn to page 29 of your 2010 Standard of Perfection, which if you haven't yet ordered I'm sure you're going to run to the APA website and do so straight away:
"All American, all English except Cornish, all French and Langshans: Feathers should be moderately broad and long, fitting fairly close to the body.
All Mediterranean, Hamburgs, and Polish: Feathers moderately broad and long, fitting rather close to the body." (SOP 29)
So basically, every single breed ever prized as an egg layer is to have feathers "fairly" to "rather" tightly fit to their bodies.
Buy your Standard and then remember this mantra: weight, type, feather, and symmetry. Repeat it over and over again until in is ingrained in your way of thinking about poultry: weight, type, feather, and symmetry.
Joseph, this post ought to be into a billboard somewhere. Truly.
