I work in Code Enforcement and while doing a search I found your webpage. The information is incorrect on the restrictions for chickens in unincorporated St. Louis County. The number of chickens allowed is 8, depending upon the size of your lot in a residential area. The same is true for St. Louis City. Roosters have NEVER been allowed because they violate the noise ordinance enforced by our Health Department. You cannot sell the eggs; chicks; or chickens even if you are registered with the Department of Agriculture. The chickens you keep and the eggs they produce are for consumption by the family members living within the home where the chickens are kept. I hope no one was inconvenience by the previous misinformation that was posted on this website.
