Effect of reciprocal Corona × Consort mating direction on hatchability and Corona/Consort phenotype distribution in Gloster canaries under ad libitum commercial feeding: a retrospective breeder registry analysis

Description

Ercan Mevliyaoğulları analysed a breeder's own registry for Gloster canaries. The fancy breed pairs crested Corona birds with plain-headed Consorts. He asked whether which parent carries the crest changes hatching success or chick type. Twenty pairs at one hobby facility in Adana, Türkiye, were followed through four breeding cycles each. The pairs split evenly between the two directions. They covered two hundred fifty-four eggs on commercial seed and egg food.

Hatchability did not differ significantly by mating direction, nor did the split of crested to plain chicks, which landed almost exactly even overall. What did move hatchability was time: success slid steadily from over ninety percent in the first cycle to about two thirds by the fourth. The author cautions that one facility's retrospective records, kept untouched as recorded, limit how far the findings travel.
