drying

I was told once by a master scorer(SCI) that antlers would shrink , some considerably, due to the drying time required for scoring hunted bucks. Does anyone know a % of average shrinkage after drying period is over? Just curious. Thanks in advance.

We have a three day old fawn that's naval cord is sticking out about 3/4 inch and still has fluid in it. You can push it in or out alittle. It needs to be dried out and sealed off. How do go about that????????
