First of all this time of year they are still nursing or just weaning fawns. plus even though it looks like they would have alot of food, the food sources they like are skimpy. add in a summer coat and they look skinny.
i have had a very nice buck feeding around the house(probably 140 +) he looks skinny and my wife made a comment about how skinny he was . i told her just give him a little time to change his coat and start eating acorns plus let his neck start swelling and he won't look skinny anymore.

but for the most part the does i have seen just look normal , i can already imagine them coated in flour and frying or maybe simmering in some gravy........well i think i will go take a package out of the freezer for dinner tonight!
