why does my chick sleep like this?
With her face into the ground? Or am I missing something?
Most chicks will sleep all the way into the ground. Or if you mean that she fell asleep in your hand its because shes relaxed!
I've seen chicks sleep every way except, well, no. There are no exceptions!
My wife freaked out a bunch of times "Is it still alive?!", and a quick poke always proved a "yes".
My favorite sleeper to date always passes out with it's head in the feeder. I even caught him getting dreary across the brooder, staggering over, and faceplanting in a fresh mound of feed.
To each their own.
