All kidding aside, you're talking about a handful of animals per acre...so you shouldn't expect any odor. This is not a Long Island duck farm, for goodness sake.Have been there several times now. There is no smell. Some believe, therefore, that the animals are really animatronic. It is either that or Disney has invented something to give to animals to prevent them and anything they leave behind from smelling.
This is the original reason why Walt designed animatronic pirates rather than employ real ones for the Pirates of the Caribean Ride.
