We have four chicks now that are 5 weeks old. Coop and run just got completed and they spent all day in it yesterday until I brought them back into the garage for the night. SoCal - High 40s at night. They seem to be doing fine inside. No brooder heater anymore and I haven't been heating the garage at night so I'm assuming they are ok to make it outside but it's going to be the same temps for the next few nights. Just looking for opinions on if they should be ok or not. I'm not worried about having to bring them in the next week or so at night until it warms up and they get used to it but they seem to love it in their new home.
