I am currently using the heating red bulb for my 3 week old chicks and it has been working great they are comfortable and sleep just on the outside ring of the light. I was wondering though, when should I start to integrate them to get used to the dark. They are in a heated basement that stays around 70 degrees maybe a little cooler but not much, should I turn off their light for a few hours in the evening? Just feel as though they should get a break from that light constantly being on. I am new to all this so this may be a dumb question lol.
