Usually the placenta comes off rather easily. Was the mare being fed fescue hay. Most foals and calves I have seen born break thier face out of the placenta before they are all the way out. Like a previous poster said, I wonder if the foal was still born. It really doesn't matter much now but it is sometimes helpful to know the next time.
There's nothing like the Rockies in the springtime... Nothing like the freedom in the air... And there ain't nothing better than draggin calves to the fire and there's nothing like the smell of burning hair. -Brenn Hill
