🧬 Chicken Color Genetics Calculator

Breeding outcomes: what colour will the chicks be?

Genotype & phenotype outcomes · Punnett squares · F2 planning

Select two parent varieties and their sex, adjust genotypes where your birds differ from the standard, and calculate expected offspring frequencies — Punnett squares, sex-linked and linked-gene handling, and F1/F2 planning. Colour descriptions and categorisation are informed by chicken-colors.info, while genotype associations draw on and are checked against kippenjungle.nl. Chicken Color Standards combines inherited components into calculated offspring genotypes and connects recognised outcomes back to their named phenotypes. Like any evolving model, it may still contain errors, edge cases, and areas for improvement. This tool is free to use, built on publicly accessible specialist references and peer-reviewed scientific literature.
Quick crosses

Select two varieties and their sex. Default is Parent 1 = ♂ Male, Parent 2 = ♀ Female — click to change if needed. Genotypes load automatically when you select a variety.

Chicken Genetics Calculator app icon
Doing this for your own flock? There's an app.

This page calculates one cross at a time. Chicken Genetics Calculator keeps your actual birds on file — colour, sex, hatch date, parents, breeding pen and photos — carries outcomes into F2 and later generations, compares intercrosses with backcrosses, and turns a goal colour into next steps: what to check first, which genes are missing, and which mating comes next. Free to start on iPhone and Android.

What the app does

A Roadmap sets out each cross and which cockerel or pullet to retain. Save a plan and return to it as your flock changes.

This is a separate example from the app, not a plan generated from your calculation here.
