What breeders are saying
Notes from the aviary floor. Real users, anonymised to initials.
“I've been breeding Spangles for nine years and this is the first calculator that actually models the Z-linked stuff correctly. The opaline split lookups alone are worth the price.”

“The Punnett breakdown matches every textbook example I tested it on. I use the share links to talk pairings through with mentees before pairing season.”

“Bought it as a gift for my dad on his 70th — he had it unlocked in two minutes and hasn't stopped sending me predicted chick portraits since.”
