We live in GA so the days are still fairly warm but our nights have hit the high 30s already. We bought some EE chicks that we received in the mail 10/16 so they're a few weeks old now. I started them in the garage then pulled them inside since the temperature dropped. I have a brooder with a heat lamp I plan on moving them to but will only be using a 100w heat lamp which won't give a lot of heat. So two questions... When could I move them back to the garage with a 150w heat lamp and when can I move them outside with the 100w heat lamp? Thanks!
