Good to know

  • Chickens count as 20 animals per animal unit, so 20 chickens equal one horse or cow.
  • Keeping livestock is not permitted in the R-4, R-5 and C-1 districts.
  • A fully enclosed pen or barn must give 3 square feet per chicken, or 15 square feet per bird where there is an outside run.
  • Separately, § 65-103 limits poultry on parcels under 10 acres to 100 fowl per 40,000 square feet.

What about ducks?

Yes on lots of at least one acre, but ducks count double. One livestock unit equals 20 chickens but only 10 ducks, and each duck needs 6 square feet of enclosed pen versus 3 for a chicken. Not allowed in the R-4, R-5 and C-1 districts.

§ 65-95A, H-I; § 65-7 (Livestock): "in the event that a property contains chickens, ducks, turkeys, geese, rabbits or small birds (such as pigeons), the following pen and stable requirements shall apply" Duck coops we build.
