Not just the cow bells, but they are complaining about the smell
In my little part of the upper left-hand corner of USANIA, when one purchases property within 1/4 mile of agriculturally-zone land, that fact must be disclosed. Part of a "freedom to farm" act meant to avoid nuisance claims.
Several summers ago, a farmer spread a considerable amount of chicken manure on his field. The aroma spread for much more than 1/4 mile.
