It's amazing, but chickens have been figuring out how to do this for a long time all on their own. They get up and eat and drink once or twice a day and really don't need any special attention. You do have to pick up eggs regularly out of any other egg boxes, because they will get up to eat and then sit on the wrong eggs. Also, after the chicks hatch move mom and the chicks out of your egg box to another location in your coop. If you let mom keep the chicks in your egg box too long its hard to break the chicks from sleeping in the eggs box at night. 4 week old chicks and mom sleeping in an egg box at night is a pile of poop in your egg box! I have a rabbit cage that I put in the floor of the coop to give mom and the chicks a semi private spot away from other hens.
Sometimes I will move a broody to another part of the coop where she has plenty of room to get up and eat and drink, stretch her legs and take care of business. You don't want to feed her on the nest or have food and water too close to the nest. As stated above, if she doesn't get off the nest to eat and drink, she could poop on the eggs and ruin them. I have also left a broody in with the general population (mainly because she wanted nothing to do with the nice little nest I made for her in the "maternity ward". She didn't want to be sequestered, I guess.) When I can convince them to be separated, I will wait a week or so to let her and the chicks back in with the flock. I used to wait until they were bigger, but learned here on BYC that mama is not quite as protective at 4 weeks as she is at 1 week (or 24 hours like my stubborn girl last year). Integrate them early, and if something happens to the hen, the chicks are already established in the flock. That's what happened here a few years ago. The hen was killed, leaving four 5-week old orphans. But they had already been accepted into the flock at a week old, so they got along just fine. You could leave them where they are and move them to floor level after they hatch. Moving her could break her broodiness. I've only had that happen once, to a hen that had been sitting for over a week. I moved her because she was in an unsafe place. Very vulnerable to predators. I hope you have a good experience with your broody!
