Personally, I feel like I love the *idea* of feathered feet, perhaps more than the reality. For now, if a chicken steps in poop I can basically just knock it off her foot without too much trouble, but the notion of having to go out there with a bucket and wash poop off of feathered feet just sounds like a recipe for more work and possibility of infection. But I know people love them!
I'm on sandy soil and use deep litter in my coop.
I find that my feather-footed birds look after their own feet without need of my interference -- which, I am told, is not necessarily the case in areas prone to heavy clay mud or wet snow, either of which can clump onto foot feathers.
