Traceability

Small practical software allowing to have the probabilities of the results of a mating according to the mutation (s) of the respective parents. It can be put on USB sticks, no need for an internet connection to use it.

Before that, we will obviously need to know the genotype of each parent. To help you determine the mutation or combination of mutations to which your zebrafinch belong, you can refer to: Illustrated glossary of mutations in zebrafinch.
That said, I would say that this application is only an aid. The best thing will always be to understand how each mutation is transmitted. For this, I also advise you to have a good basis to consult the article: Zebrafinch genetics : Instructions.

Here is a site, also available in application, dedicated to the calculation of the genetics of zebrafinch. ZebraCalc allows you to have the probabilities of results depending on the mutations of the respective parents.

1. Benefits of ringing your zebrafinch

This will allow you to know their year of birth and to identify them, which will be essential for establishing a genealogy and monitoring your breeding. Each ring will be the identity card of each of your zebrafinch.
In addition, if you wish to have one of your zebra finches compete, only those who are ringed can participate. The ringed zebra finches of the current and previous year are eligible to participate in a gathering.
Then, a breeder will always prefer to buy a ringed zebrafinch on which he can be sure of the year of birth of this one and be informed of its origin.

Advice from an experienced breeder :

"You should encourage zebrafinch breeders to sell birds with a pedigree sheet, even "homemade" with phenotypic color indications, guaranteed litter colors, possible litter colors .... And the same information on parents. ... And display in your breeding, in gold lettering (or in paint) above the breeding batteries "A COMPETITION BIRD MUST HAVE A CHARACTERISTIC PHENOTYPE OF THE MUTATIONS THAT MAKE IT UP and KEEP THE TYPE OF THE ZEBRAFINCH !"

In order to improve traceability and reduce unpleasant surprises during mating, here is a model of the zebrafinch transfer certificate :
