Well, I decided to get 3 cornish x (have 3 layers coming next month) and got a freebie so I now have 4 lil chicks in an old foot locker in my "sunroom/mudroom". This room is not insulated and is all windows so the temp isn't regulated. Depending on weather it can get very warm just from the sun but right now, it is cold but doesn't have the cold from the wind and a plain wood door separates it from my kitchen. They have a 250w red light suspended in there and think I may need to lower it for night time temp changes? Is this correct or should I try to get them adjust themselves. Or should I wait to "let them adjust on their own" when their a little older? Even though my head was ready to explode with all the reading I have done on here prior to getting them, I now know that all the reading in the world never prepares you for chicks...hmmm same goes for kids lol!
