I have ten baby Delawares. Nine of them are pretty normal. The other one chirps constantly, like there's something wrong. It's a bit unnerving because every once and awhile, while she's crying wolf, one of the others will wiggle out of the box and be really calling for help and I can't tell. I notice that she does quiet down when the others are all cuddled around her, like when its dark or they're sleeping, or when I hold her. I've got heat in there, and I can't see why she'd need it more than the other nine, but I'm wondering if she needs it. For what it's worth, she was the last out of her egg too.
