Calculator

Flock uniformity calculator

Paste weights from a bird sample — we compute the coefficient of variation (CV%) and the share of birds within ±10% of the mean.

verifiedFrom the team that has organised work on poultry farms for years.

CV%UniformityNo sign-up

Flock uniformity shows how even the birds are by weight — the lower the CV%, the more uniform the flock. Paste your sample weighing results (50–100 birds recommended), separated by space or newline.

E.g.: 2.41 2.38 2.55 2.29 ...

Coefficient of variation

Fill in the fields to see the result.

Indicative result based on breed curves (Aviagen Ross/Cobb, Aviagen Turkeys) and public factors. Real values depend on the flock and conditions. The calculator sends no data — it computes in your browser.

FAQ

How many birds should I weigh?add

A recommended sample is 50–100 birds randomly picked from different parts of the house — a larger sample gives a more reliable result.

What CV% is good?add

As a rough guide: up to 8% is very good uniformity, 8–12% average, above 12% poor — but always compare against the norm for the specific breed and age.

What unit should the weights be in?add

Any — kg or grams, as long as all weights use the same unit.
