So one of our 3 new baby chicks seems to fall asleep more than the other two, and her head always droops forward and rest sideways in a strange kind of way. I'm just wondering if this is something I should be concerned about. She wakes up quickly to stimuli and seems perfectly alert while not asleep. Also, their box is in an unheated but closed garage with a heat lamp about 14" above the surface. Is this a safe environment in... say 43˚F weather?
