Winter brooding question: keep ~a dozen chicks in the incubator or buy a brooder?

[hatchbloom]

Hi all! I’ll have about a dozen chicks hatching. The incubator has heat and ventilation. With winter temps and a cool room, is it safe/practical to brood them in the incubator for a while, or should I move to a brooder right away?

They can stay in the incubator for a day or two, but the brooder is preferred
