Oyster stout brew

So what i did was make my oatmeal stout and add the 1/2 lb of oyster shells in at 15 minutes left in boil. I mashed high 158f and pitched US-04. Fermented about 66°. My calculations said FG 014 it reached .011 in 3 days. Very surprised. Do you think the calcium and minerals in the shells fed the yeast? Hopefully its stable. Its not supposed to be a dry stout
