I do leave my broody and babies in the same area. The way my set up is in 1 coop I can close a screen door and separate momma and babies, which I did for about a week. Then I left the screen door open and didn't have any problems. In a different coop I didn't do anything to separate momma and babies from the rest of the flock. I didn't have any problems with them at all. I put out chick starter or broiler crumble and try to position it inside a wire cage that the chicks can enter but that the larger birds can't get in. That seems to work well.
Also, momma was able to take the chicks outside whenever she felt it was time. I think she waited a week or 10 days. Before that they just wandered all over the 10 x 10 coop.
I agree with the previous posters in regard to determining when a broody is serious. Mine would peck at me and get angry if/when I took eggs out from under her. She also stayed on the nest almost 24/7. She would get off for about 15 minutes a day. I do want to set up a better setup so that the other hens can't lay their egg(s) in with the broody. I had that happen a lot and unfortunately took out the wrong egg(s) a couple of times, even after I had marked them! Even the permanent marker disappeared on a couple.
