got this from a website
We just let our hen sit on the eggs in the nest box, but it's best to move her and the clutch of eggs to a larger nest box of at least one foot square so that she can turn around and move a bit, and set up so that the chicks have enough room to access food and water within reach of the nest box once they're hatched. She will want to be cozy and she will not want to be moved! She will probably peck you if you try to move her so wear gloves. Make sure that the floor of the nest box has soft cushioning like shavings or straw. And you will want to make sure that she can't be messed with by the other hens. If you can put feed and water right in front of the box for her for the duration of her setting (but where she can't knock it over into the eggs), that will also help, as she will only get off the eggs once a day to poop, eat and drink.
hope it helps!
