This platform synthesises the expert knowledge base of chicken-colors.info — a reference built by experienced breeders and geneticists, combining decades of previously scattered knowledge into a single verified source. Each color variety entry contains genotype data sourced and verified by breed specialists.
The tools here are designed for breeders at all levels: whether you are trying to understand the genetic difference between two similar-looking varieties, plan a breeding cross, or identify which standard your birds conform to.
New to colour genetics? The Genetics Guide explains the whole system from the ground up — the two pigments, how genes and alleles work, and the loci behind every variety.
Developed by Dr. Anne Rainville, as part of the Wolfhoeve breeding programme. Feedback via wolfhoeve.nl.
Select two color varieties and compare their breed standards side by side — genotype differences, phenotype descriptions, and AI-generated commentary on how to distinguish them in practice.
Select two parent varieties, adjust genotypes where your birds differ from the standard, and calculate expected offspring frequencies — including Punnett squares, linked-gene handling, and F2 planning.
Upload one photo of your chicken and see which color varieties it lines up with — free, no sign-up.
All three tools are completely free to use — no account, no sign-up — and are informed by publicly accessible specialist references and peer-reviewed research, credited throughout.
Make better breeding decisions without spending hours untangling complex colour genetics. Keep your flock on file — colour, sex, hatch date, parents, clan and photos — calculate crosses across generations, and turn a goal colour into next steps: what to check first, which genes are missing, and which mating comes next.
