I never had mine close enough to the chicks but didn't get very many last year, will probably take the incubated chicks hatching soon and put them in the insulated shed with the others if the broody will accept them, but the ones under the broody 4 days old aren't under her much, she's showing em where to find safety now as they are all eating, drinking,scratching and running every where as they don't wanna wait for momma.
