In Danbury, city leaders are concerned about a proposal to allow chickens as pets in residential areas. They claim the birds are health risks…. and warn of potential disease transmission, pest attraction, and environmental concerns. Some city officials even say that the proposal violates state codes regarding organic waste and nuisances. It all stems from a request by one family to classify chickens as pets rather than farm animals. That family argues that the current rules unfairly penalize Danbury residents who keep chickens as pets. The city’s Planning Commission will review the request next week.
