I just went to check on them and be a nerd watching them wiggle, and one of them cheeped so loud it freaked me out and I ran into the front room. My husband thinks I am insane, because it had stopped (of course) by the time he came to see. How long before they hatch do they cheep? I have a chorus of cheeping if i put my ear to the incubator, but the super wiggly one is noisy!
