There is no ethical issue with shooting a bedded deer whatsoever! Ib bird hunting a roosting bird or a duck on the water, yes, thats not sporting! The "sport" of deer hunting is either getting close without being spotted, (which if its bedded, you've obviously done!) Or shooting a calm animal! Unless you are just one of the really good shooters, shooting a running deer would be much more of an ethical question than shooting a bedded deer. Also, what would be more unethical, shooting a bedded deer, or trying to make a super long shot? Not that long shots are unethical either!
