Mine were out in the coop at two weeks with a heat lamp of course, and it was getting into the 30's and 40's here. I would at least put yours out during the day, to give them a little more space.
As long as it stays warm enough under the lamp, they would be fine in a draft free coop. I always aim for 100 degrees under the lamp, that way if they do get cold, they can get warm quickly. With 24 babies (if I read your post correctly) I would put up 2 lamps.
