Are the ISA Browns ready for outside? I like in middle GA and outlet load are 50 degrees at night. They have a solid wood coop with hay. Can get go outside at night now? There are six of them and they are getting too big to be inside now. I am not sure of the age but 5 weeksish maybe? There are smaller chicks the RIRs in the photo that are not ready yet. I’m just looking for info on the ISAs. They have been outside during the day time for weeks and are used to outside.
