Well it depends on the run type. Mine is movable and I don't clean it often I leave the poops there it's a natural manure that aid in enriching the soil and also allow the growth of insects and worm 😊😊
It is advicible to let nature take play it's part as the hen will leave the nest any time she feels it's okay to poop or eat this happen instinctively
All you can do is to provide her with food and water but not close to her nest so she doesn't ruin her eggs 👍😘
