We have four eight week old chicks. For the last couple of weeks we have been letting them outside all day and then bringing them in at night. We just finished there tractor type coop and was going to have them sleep outside tonight. After dark they were huddled on the ground by the door wanting to be brought in. We put them on the roosts and they got down and came back to the door. We gave in and brought them in. Is it normal to have to "train" them to stay outside? If so what do we do just leave them out cold turkey? We live in Arizona and the highs are in the 70's and the low is around 42.
