Overfeeding chickens

Employees can't stop spreading chicken feed. Does not matter if it is a hired rancher or a employee of a small business or whatever,  they constantly feed the chickens when none of them are hungry and they have like 50 piles already on the ground.

I saw a bug report about this that was 5 years old and there was no vote button so since this is still happening I am begging you to fix this again. My yard is nothing but chicken feed.
