ニワトリのヒナの雌雄鑑別
1. Chick sexingChick sexing is the method of distinguishing the sex of chicken and other hatchlings, usually by a trained person called a chick sexer or chicken sexer. Chicken sexing is practiced mostly by large commercial hatcheries, who have two different feeding programmes, one for the females (or hens) who are destined to lay eggs for commercial sale, and the others for the males, most of which will be culled within days of hatching because they are irrelevant to egg production.
