I'm not quite sure what you mean, but if you have a broody hen with chicks she hatched she will raise them. This means she will keep them warm and show them how and what to eat and drink, and defend them the best she can. When they are somewhere around 6 weeks old she will stop letting them sleep next to her and follow her around and they should be OK getting around on their own by then.
All you have to do is provide mother and chicks a safe, low to the ground nest space with shallow dishes of food and water nearby which usually need changing/topping up frequently because chicks are messy. They also need to be kept safe from any other chickens you have, because the chicks are vulnerable particularly in the first 1-2 weeks.
