I keep reading that happy chicks are quiet or chirp softly. Mine are neither. They're quiet when they sleep, but when they're awake, they're constantly, constantly making chirps, trills, peeps. Not particularly in a hollering for mom sort of way, but NOT soft or quiet. This is my first batch; there's eight of them, about 9 days old. They're in an 18"x36" brooder made out of two cardboard boxes. I had them in a Sterilite tote, but they seemed to need the height to hop up on their heated tunnel and flap around a bit. I can't tell if they're nervous, or excited, or bored? Or just want to see out because the Sterilite was clear--cardboard, no so much. Occasionally one or another will do more intentional and loud peeps, repeated several times and evenly spaced, but it seems half they time they are trying to get the other chicks' attention. Are they ok? How do I tell if they aren't? I'm feeling pretty clueless right now!
