I just turned out their light in the room/broader area. My question is their 4 weeks old and do baby chicks get up in the night if their hungry to go eat? Or do they sit there all night until the morning time? Some have said they dont have good eyesight so will sit in the same spot until the morning. I have a dim light reflecting into their room/broader area but its very low,low lite. Should I wait a few hours longer before turning their light off? I turn it on at 7am and just turned it off at 7:30pm.
