Hi all! We brought home 8 chicks yesterday! I'm new to the chicken game so any tips are welcome! As of right now they are in a dog crate with feeder, water and heat lamp in our garage. How long do I have to get a coop built? Also how critical is it to maintain a hot temp for them 90 F. It gets in the 40s at night but the heat lamp does stay on! Will they be good for now? Thanks for any advice!
