I'm SO glad to know it's not just me. I've been playing happy/tid-bitting hen noises, sounds of hens coaxing eggs to hatch, other chicks chirping in egg noises, and talking/singing to them.

I'm always singing. I have a 'kitty nap time' song that one of our cats, Love Bug, will zoom into my room when she hears it to lay down for a nap with me. She's serious about her beauty sleep.
Thank goodness I took a late nap! I'm DYING to know who it is. Every time I look, it's quiet so I can't even see if any of the eggs are wiggling at all. Mischievous babies!
