Typical city rules
Oregon State University Extension's Raising Chickens in Urban Environments (EM 9089) notes that most cities ban livestock but usually tolerate a few backyard chickens if local rules are followed, while some cities allow none. The rules it says are common:
- Flock size: a cap on the number of chickens.
- No crowing roosters.
- Setbacks: typically 10 to 25 feet from property lines, varying by city.
- Screening: OSU recommends a privacy fence or shrub screen at least 4 feet high around outdoor enclosures.
OSU also observes that authorities usually learn about backyard chickens only when neighbors complain, which makes neighbor relations part of compliance.
Space
| Item | Figure (OSU EM 9089) |
|---|---|
| Floor space, permanent confinement | 1 sq ft per pound of body weight |
| Typical hen weight | 4–6 lb, so about 4–6 sq ft per hen (bantams less) |
| Air space in enclosed coops | At least 3 cu ft per pound of body weight, with venting |
| Heat | May be needed where winters reach single digits or below |
- Coop: protects from weather and predators
- Floor: about 1 sq ft per pound of hen (4–6 sq ft per hen)
- Screen or fence at least 4 ft high
- Setback from property line: often 10–25 ft
Feeding, briefly
University of Maryland Extension calls commercial complete feed the most convenient way to feed a flock, chosen by age and purpose (starter, grower, layer and so on). Scratch grains are "not necessary when birds are receiving a complete diet"; if fed, limit them to what birds eat in about 20 minutes, roughly 10–15% of daily intake. Table scraps should stay occasional. Birds need insoluble grit, which free-ranging birds usually find themselves. Herbs as treats are covered on the herbs and backyard poultry page.
Know the plants in reach: NC State Extension's Richmond County office lists plants toxic to chickens, including oleander, yew, castor bean, nightshade fruit, milkweed and tobacco, and notes the list is not complete.
Hygiene
The CDC's backyard poultry guidance, aimed at preventing illness spread from birds to people, advises:
- Wash hands with soap and running water after touching backyard poultry.
- Don't kiss or snuggle birds and then touch your face or mouth.
- Keep poultry out of the house, especially where food is prepared or stored.
- Don't let children younger than 5 handle chicks, ducklings or other poultry.
- Keep a pair of shoes for poultry chores and leave them outside.
