About poultry in the United States
Backyard poultry (chickens, ducks, turkeys, geese) has exploded since 2020 — 13% of US households now keep chickens. Our poultry calculators cover hatching, coop sizing, feeding across all life phases, and breed-specific first-lay ages.
What every backyard chicken keeper should calculate
Coop + run size (undersized leads to pecking and egg-eating), feed amounts (varies 0.25–0.33 lb per hen/day by breed), hatch date if incubating (21 days chicken, 28 duck), and laying age (16 weeks for Leghorns, up to 32 for Brahmas).
Poultry calculator FAQ
Do I need a rooster for eggs?
No. Hens lay eggs whether or not a rooster is present. Roosters are only needed for fertilized (hatching) eggs. Many municipalities ban roosters entirely due to noise.
How many chickens can I keep?
Depends on local zoning and coop space. Standard: 4 sq ft coop + 10 sq ft run per bird. Most backyards comfortably support 3–6 hens.
How accurate are these calculator results?
Our calculators implement the exact formulas used in veterinary textbooks, AAFCO/NRC nutrition standards, AAHA/AAFP life-stage guidelines, and peer-reviewed research. Results are accurate within the precision of the input data. For medical decisions (toxicity, drug dosing, diabetic insulin), always confirm with your veterinarian — calculators are educational tools, not clinical devices.
