I read a thread where somebody almost lost a chick because it got caught up in the mother's feathers when they were under her and she got up to go eat or something. They found the chick before it died. Actually, more than one person said that happened to them, too. Maybe she got caught in the mom's feathers and then fell off when the mom accidentally dragged her outside. Just another possibility. Just take care of that poor wee little one. That's a silkie, isn't it? Soooo sweet!
