Which Came First? In This Case, It Was The Chicken

Live chick born by mother hen: image via bbc.co.ukWhich comes first; the chicken or the egg?  The way biology intends it, it's the egg.  The mother hen lays the egg, incubates the egg by sitting on it and, within some days, a live little chick hatches out of the egg....

But something went awry with a mother hen in Sri Lanka who gave birth to a live chick instead of an egg.

This mother hen, according to the Sri Lankan official veterinarian's report, incubated the egg inside her for 21 days.  The egg hatched inside her, and eventually she gave birth to a live chick, fully formed and healthy.

Hens are apparently not physically capable of sustaining the acitivity of a live chick within their wombs; the poor mother hen died  from internal injuries.
