Budgie Genetics Calculator
Why make this a breeding reference, not just a percentage calculator?
The most useful part of a genetics calculator is not a single percentage — it is understanding what that percentage means for the pairing. Park Ridge uses the calculator as a planning aid alongside parent records, known splits, chick photographs and actual breeding results.
Start with a project preset
Choose a common Park Ridge project bird to load its starting traits, then adjust anything that is different in your actual bird.
Enter known splits honestly
A suspected split should not be treated as proven. Use the calculator to explore the possibilities and update your records when breeding evidence confirms them.
Read sex-linked traits separately
Opaline, Cinnamon and Ino are sex-linked, so the calculator reports sons and daughters separately rather than mixing them into one percentage.
Compare prediction with reality
The real value comes from recording what the chicks actually become. Use Real Breeding Results to compare expected outcomes with your documented clutches.
Use the Park Ridge Budgie Genetics Calculator to explore expected chick outcomes from a breeding pairing. Select project-bird presets or enter visible traits and known splits manually, then compare the percentages with your real breeding records. The calculator is designed around practical Heritage Clearwing breeding, including base colour and dark factor, Violet, Whitecap, Yellowface/Goldenface, Clearwing, Greywing, Cinnamon, Opaline, Fallow, Ino, Dilute and Pied.
Ino note: Ino is a sex-linked recessive mutation, not a form of Fallow. It is listed immediately below Fallow in the pairing controls for convenience. The calculator treats Ino separately and reports cock and hen outcomes according to sex-linked inheritance.
Expected Results
Choose the parent traits above and press Calculate Pairing. The result will include percentages, plain-English explanations, breeder notes, and record-keeping reminders.
How to Read the Calculator Results
Percentages are estimates
A 25% result does not mean every clutch of four will show one chick of that type. It means each chick has that chance when the parents are entered correctly.
Unknown splits change everything
If a parent is split for Clearwing, Opaline, Cinnamon, Fallow, Dilute or blue, the real nest results can be different. Use Unknown when you are not sure and update records when chicks prove a hidden trait.
Sex-linked traits must be read by sex
Opaline and Cinnamon are sex-linked. Daughters depend heavily on what the cock bird carries or shows, while sons can carry hidden splits from either side depending on the pairing.
Use results as a planning guide
The calculator helps plan pairings, but real breeding records are stronger evidence. Compare the result with ring numbers, photos, hatch notes and chick colours before changing labels on parent birds.
How to use this calculator
Use known facts only
Select Unknown when you are not sure. A hidden split can completely change nest results.
Track every chick
Use the result as a planning guide, then compare it against your clutch records and leg-band notes.
Check sex-linked traits carefully
For Opaline and Cinnamon, daughters can only show the trait when the cock bird passes it to them.
Use presets as shortcuts
The Amethyst, Cobalt, Goldentop, Green series, Mauve, Olive, Rainbow, Red Violet, Seafoam and Violet presets fill the main fields quickly, but you should still adjust splits and unknowns to match your own bird.
