Warning: the photos below are of a dead duckling - dont look if you are easily upset.


Hi guys, I am posting this because it is scientifically interesting although emotionally upsetting.

I have a family of runners one of which has the balinese pompom on the side of her head, I incubated some of her eggs, the photos below are an interesting example, albeit a sad outcome, of the Balinese skull malformation.



The skull hasnt formed around the brain of the bird and the duckling died at day 22-24 of incubation.

Does anyone know what the odds are of this malformation? She is the only one of my flock who shows the pompom but as it is a resessive gene, I guess at least one of my males is a carrier without displaying the trait.
