So I just picked up my first chicks ever from Cackle Hatchery, and I've been staring at them in the brooder nonstop ever since! They are all doing great so far. I have a Premier heat plate in there for them. Even though it's in the 90s today, a few of them have been going under it. My question is, are you supposed to adjust it to their height when they're standing up or laying down? I noticed the ones that are asleep under there are sleeping standing up so that their backs are touching it. Should I lower it a little so that they can lay down and still be touching it? Sorry for being such a newbie!
