I put my 4 barred rock chicks out in the coop at 5 weeks old. They absolutely love it, and are doing wonderful. I've also got 4 bantam orpingtons who are outside in my garage with no heat lamp, and they are doing great too. It sometimes just amazes me at how "technical" everything has become. I love my chickens dearly, but I do think that you can pamper them too much. Geez, how did people raise chicks before there were heat lamps?
