FLChickens that is alot of cute babies. Congrats to you!!
My 1st baby is now fully out of shell but it looks like a yellow/white thing still attached. Is that the yolk sac? And will it be ok if it is not absorbed? It's also shivering is that normal?
It needs to dry and fluff out in the bator where it is nice and warm, the dangly part sound like where it was attached to the egg and will be fine and gone in no time.
