Mine have been doing the same thing, and are the same age as yours. I'm wondering if I should turn mine down too? They hang out on top of the cave a lot during the day. But not at night. Am I doing something wrong? I made it taller for them, but they would still need to crouch a little to get under it. Should I raise it more?Last night my older chicks did not go into the cave. They stayed outside in a corner of the cage (Blooie they are in a MUCH larger cage now. They huddled together and the only sounds I heard were those little happy cooing noises chicks make. They are fine this morning, playing and chasing each other, mock fights and so on. I have a feeling I was over heating my chicks with the heat lamps.
I'm going to turn the heating pad down a notch now. The oldest were hatched Jan 24th. The younger 3 about a week later.
I really like this cave. My hatch from Friday are loving their cave. The take to it just like it was a hen..
Thanks Blooie!
