I have my last group of chicks coming next week (July 18-22). Two buff brahma roo, two columbian wyandott, four redstar. Since it is plenty warm outside (expected upper 90's into low 100's) for the next week and 90's for the rest of the month and first of part of August; do I still need to brood the chicks in the house with heat lamp? Or since it is summer and lots of warm: can they go outside in a safe container? It would have chicken wire or hardware cloth, part of it will be plywood and would have shad covering too. Something similar to rabbit hutch. Most likely 6 feet long, 3 feet wide, 3 or 4 feet tall. They are hatchery chicks, so will only be a couple days old when I get them.
