Howdy, our furnace went out and will be out for 3 days before it is completely replaced. Between heat lamp and ceramic heater in the room we are getting good heat, but it fluctuates throughout the day as the wind, sunshine, and outside temp changes. No fast temp swings, just everytime I check the room and the brooder it is a little different by 10 degrees. Chicks are 2 weeks old. Is that a problem?
