What ducks do in there is they will enlarge that hole as they spin, they dont turn quite like a chick inside, and the spinning actually helps cut off blood supply down at their umbilicus. that's why its such a hard call with ducks, they could have no more blood in the membranes but still not have absorbed all the sack.
