Overview
The retained source records describe the White Leghorn as a heritage white-egg breed in the Mediterranean class. Cackle Hatchery calls the White Leghorn an active forager and estimates annual production at 280–320 eggs. Townline Hatchery's White Leghorn record lists 280 eggs annually. Those entries describe the hatcheries' variety-specific catalog records; they are not a promise for every hen or flock.
Egg records
Cackle's retained White Leghorn record says the birds lay white eggs and gives an estimated range of 280–320 eggs per year. The range is stored as numeric lower and upper values, with the unit recorded separately, so the chart and quick-facts table do not have to extract numbers from display text.
Townline's record gives a single annual figure of 280 eggs. The lower end of Cackle's estimate and Townline's figure therefore meet at the same value. This page keeps both records visible instead of turning them into a new average or choosing a larger number for a headline.
An annual catalog estimate is a description of the source's listed output, not a guaranteed result. The evidence retained here supports the two displayed estimates and the white shell-color label. It does not establish a weekly rate, a lifetime total, or a comparison with another breed, so this profile makes none of those claims.
Mature weight and laying maturity
Cackle lists a mature hen at 4.5 pounds and a rooster at 6 pounds. Townline independently lists the same two weights: 4.5 pounds for females and 6 pounds for males. The quick-facts table preserves both source records even though their numeric values agree.
Townline lists maturity at 18 weeks and also describes laying as starting at 4.5 to 5 months. This page stores the explicit 18-week value as the maturity fact. It does not convert the month range into a second week estimate, because doing so would add a calculation that the source did not publish.
The retained facts support only the listed sex-specific mature weights. They do not establish a body-size category, feed use, space requirement, carcass value, or growth curve. Those subjects are deliberately absent rather than inferred from the two weight figures.
Other sourced fields
Cackle identifies the comb as single, the show class as Mediterranean, and the breed type as heritage. These are categorical catalog fields. They remain strings rather than being converted into scores or used to imply suitability for a particular household.
The same Cackle White Leghorn snapshot uses the phrase "active forager." It also says the birds usually do well in hot weather because of their lighter bodies and Mediterranean background. This page reports those phrases at source scope and does not extend them into handling, housing, cold-weather, or care instructions.
The evidence table is intentionally narrower than a conventional breed profile. Claims about behavior beyond the cited phrase, broodiness, flight, feed efficiency, medical care, or housing were removed because the retained fact ledger does not support them at publication standard. Readers can open each source link beside a quick fact and compare the quoted record directly.

Flock size calculator
Enter your household size and target egg output. The calculator returns the flock size and space you'll need based on the productivity tier you pick.
Hens needed: 2
(4 × 2 eggs/week / 6 eggs/hen/week, rounded up)
Coop space: 4 sq ft (2 sq ft/hen × 2 hens)
Run space: 20 sq ft (10 sq ft/hen × 2 hens)
These are minimums. Most backyard keepers give 1.5–2× this much space, especially for run area, to allow range rotation and reduce feather-picking behavior.
Where these numbers come from
- Low tier 3 eggs/hen/week — Egg Production: 150 – 280 eggs per year www.cacklehatchery.com
- Medium tier 5 eggs/hen/week — Egg Production: 200-280 eggs per year www.cacklehatchery.com
- High tier 6 eggs/hen/week — Cackle lists White Leghorns as producing large to extra-large white eggs, with an estimated 280–320 eggs per year. www.cacklehatchery.com
- Coop 2 sq ft + run 10 sq ft per large chicken (minimum) — A small bantam chicken needs a minimum of 1 square foot of indoor space and 4 square feet of outdoor space, while a large chicken needs a minimum of 2 square feet of indoor space and 10 square feet of outdoor space. extension.msstate.edu
