I am trying to get my Rocks out to the barn this week as they are getting too destructive for my brooder. The room they are in is about 68 without heatlamps / lighting. It is currently 58 in the coop. (Draft free and dry) I cannot put heat lamps in the coop. If I transport them in a two boxes and then let them acclimate for an hour or so in the box, would they be ok?
