We are first timers here and have 6 chicks that are living in a large dog cage in my basement. They are about 4-5 weeks now and are doing well. My shed to coop conversion is done and I was wondering when I should move them out. I will move the red heat lamp out with them when we move them. I'm worried that the shed is so large and its about 40 degrees out at night right now. If I place the lamp near the floor will they huddle near it if they get cold or will they just roost high away from it and freeze? They aren't fully feathered yet. They have wing, back, some breast feathers but aren't completely feathered out yet.
