Health of the bird is primary and standing on wire will create foot issues including bumblefoot.
Beyond that, chicken poop will not fall through 1/4 inch wire. It won't fall through 1/2 inch wire. Chicken poop can be rather solid and droppings from full size birds can be substantial in size. You're going to have chicken poop embedded, dried, and caked in that wire in no time flat.
There's a reason you've not found much about this online. While good in theory, it isn't practical.
Well that sinks the reasoning behind the idea. Thanks!
