Eggs covered in poop!

So I have 11 hens, and I think somewhere around 7-8 of them are laying. I think 2 just started, and are laying poop smeared eggs. Most of my hens are polite enough to lay in the nest boxes, but each day for the last week I've found 2 eggs laid right in the coop floor, no where near the egg boxes, and the eggs themselves are covered in poop smears all over the shells. Is this a sign of a new layer? Or a sign of a problem with laying? There's no pile of poop on or around the egg, but the eggs themselves are in the middle of the coop floor and encrusted all around with poop. What gives?
