I'm a new chick Mom, and am still learning the ropes of these sweet little fuzz balls. I've read about how chickens are so deeply asleep at night, they can even be picked up and moved without being woken up. But my little babies (just 1 precious week old now) seem to be awake every time I open the door (no matter how quietly I do). My brooder is in a heated shop off of the garage, and the door, while heavy, is relatively quiet. I like to monitor their temp. and condition, especially before I go to bed at night. But even when I quietly sneak in, sure I couldn't have awakened them with my quiet noise, I'm greeted by little eyes. Am I disturbing them awake, or do they (similar to human babies), sleep more and more at night as they age?
