'Eggless' chick laid by hen in Sri Lanka

The "eggless" chick has survived, but the mother has died A Sri Lanka hen has given birth to a chick without an egg, in a new twist on the age-old question of whether the chicken or the egg came first.

Instead of passing out of the hen's body and being incubated outside, the egg was incubated in the hen for 21 days and then hatched inside the hen.

The chick is fully formed and healthy, although the mother has died.

The government veterinary officer in the area said he had never seen anything like it before.

PR Yapa, the chief veterinary officer of Welimada, where it took place, examined the hen's carcass.

He found that the fertilised egg had developed within the hen's reproductive system, but stayed inside the hen's body until it hatched.

A post-mortem conducted on the hen's body concluded that it died of internal wounds.

The BBC's Charles Haviland in Colombo says that the story has made headlines in Sri Lanka, with the Sri Lankan Daily Mirror's concluding: "The chicken came first; not the egg."

據英國廣播公司4月19日報導,斯里蘭卡的一衹小雞近日引起各媒體關注,因它沒有經過孵蛋的過程出生,而是直接從母雞體內降生了。

據報導,小雞雖然安全降生而且非常健康,但母雞分娩後就死了。一位醫生評論稱,受精卵子在母雞生殖系統內發育了21天,最後在體內直接完成了孵化。

斯里蘭卡《每日鏡報》調侃道:對於先有雞還是先有蛋這個古老問題,現在這件事給出的答案再明確不過了──當然是先有雞,後有蛋啦!
