I also agree with minimum interference. I find the more I interfere the more harm I potentially do. Broody hens have been doing this a long time without human help.
I let my broodies hatch with the flock in nests a bit above the coop floor. After they hatch and the broody brings them off the nest, I have food and water on the coop floor where the chicks can get to them. That's pretty much the end of my helping Mama raise the chicks.
It will depend on your facilities, but what usually happens with mine is that Mama keeps them in the coop for a couple of days before she takes them outside. My pop door is about a foot above the floor so I use pavers to build a staircase for them inside and out to get up and down. That may have an effect on how long it is before she takes them outside. After she takes them outside, she pretty much takes them outside every day all day.
At night they sleep on the coop floor, usually in a corner but sometimes she just beds down with them right in the middle. I do not provide boxes, nests, or anything else. I find Mama doesn't need them. The hen brings them in before dark. The hen provides all the warmth they need.
Sometimes, when my coop is pretty crowded, I put the hen and chicks in an outside shelter in the run after she brings them off the nest. If I leave them locked in that shelter for two or three days and nights Mama will take them there to sleep instead of back in the coop. I can lock them up safe from predators. When I'm comfortable Mama has imprinted on that shelter as where she should take the chicks, I just let her and the chicks roam with the flock during the day. I do have a nest I put in there for Mama to use. Sometimes the broody hens use that nest, sometimes she doesn't. The purpose of that nest is to give Mama a dry place to go in case it rains hard enough to flood.
I don't know what your coop looks like or how much room you have outside either. I don't know if one way is better for you compared to any other way. There are benefits, inconveniences, and risks associated with any of them. I find the more room they have the easier the entire process goes. The broody needs some room to work but the time the extra room really comes in handy is after the hen weans them and leaves them alone to make their way with the flock. She has already taken care of basic integration so I don't have to worry about that, but they still have to manage their pecking order issues. In warmer weather I've had broody hens wean their chicks as young as three weeks and they've made their way with the flock fine, but I have lots of room.
