I am a new chick owner and am staying up all night to check the temp in our outside house which is enclosed but with little airflow. During the day it can get up to 85-90degrees but at night it cools way down to 50-60degrees. So, I put in a fan (don't laugh) and a heat lamp. But... now I am obsessing about the temp and at the same time driving my husband crazy (he bought the chicks for me and thought I'd just throw them outside when they sported a few feathers and that would be that). WRONG. Can they get too cold? What is too cold? Can they get too hot? What is too hot? HELP! (If these ?'s have been already answered, sorry but I'm new to this...).
