Backyard chickens in Dayton, Ohio

Yes. The City of Dayton, Ohio permits residents to keep backyard hens. Multiple sources reviewing Dayton's animal-keeping code (Chapter 91, "Animals") confirm that chickens/fowl are recognized as animals that may be kept in an enclosure so long as they are given "wholesome exercise and change of air" (§ 91.02(4)), and a resident who read the current code directly reported finding no blanket prohibition on keeping chickens or fowl in the city. However, roosters are not permitted — this is consistently reported across independent sources describing Dayton's ordinance. The code does not appear to set a specific maximum number of hens; several independent guides note that "the exact number of chickens allowed isn't explicitly specified" in Dayton's ordinance, so zoning/nuisance provisions (not a hard headcount cap) primarily govern how many birds a household may keep. Older ordinance summaries reference a keeping location restriction (cited as "Ordinance 92, § 18: A. Fowl") stating that "No person shall keep chickens or other poultry in any dwelling or within one hundred feet thereof", i.e., coops/pens must be kept at a distance from dwellings rather than inside them. General nuisance, noise, and sanitation rules also apply: Dayton's code prohibits keeping any animal in a way that becomes a public nuisance or disturbs neighbors (§ 91.10, § 91.17), and separately regulates the sale of baby chicks in lots of fewer than six (§ 91.04). Because sources vary somewhat on the exact current section numbers (the code has been renumbered over time) and on whether a permit is required, prospective keepers should confirm current requirements with Dayton's Building/Zoning or Code Enforcement office before starting a flock.

Dayton has cold, often snowy winters (occasional sub-0°F cold snaps) and warm, humid summers with temperatures regularly in the 80s°F. Coops should be insulated or at least wind-proofed for winter and well-ventilated for summer humidity, with attention to preventing frostbite on combs/wattles in the coldest months.

Southwest Ohio's mix of urban and wooded/riparian corridors (like those along the Great Miami River) supports healthy populations of raccoons, red-tailed hawks, red and gray foxes, opossums, and coyotes, all of which will target unsecured coops or free-ranging birds, especially at dawn/dusk. Secure, hardware-cloth-covered runs and a predator-proof coop are strongly recommended.
