Ducklings carrying both genes (homozygous) for the crest do not survive to hatch. Of those that do hatch, typically 1/3 of them will not have crests. It is easy for breeders to determine how the crests will develop on the newly hatched duckling, so that they can select stock to raise and sell off the rest as day-old ducklings. Lay Blue
