Hen lays healthy 'eggless' chick

Which came first, the chicken or the egg ? One hen has turned the age-old question on its head.
Vetinary officials were shocked when they were called to examine a hen that had given birth to a healthy, live chick. Instead of being laid in an egg and incubated outside the hen, the chick was incubated inside the mother before being born outside of its egg. Unfortunately the hen later died of internal injuries, but the chick continues to thrive and seems otherwise perfectly normal.
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.

But the chick needs air to survive. If it is in the egg outside the chicken it receives air through its shell. Inside the chicken there is no source of oxygen. The chicken and chick are not connected by am umbilical cord so it cannot receive a source of oxygen through the mother's blood supply. It would suffocate in there. I'm going to guess and say the egg was at the hole where the egg comes out, but was stuck. So there was still enough egg surface protruding to allow air to pass through the shell. The shell allows air to pass by the process of OSMOSIS.

maybe as the egg formed so did the chick, hence the egg is laid you have instant chicken ?.

This thread is making me hungry for some chicken tenders. Is that young survivor ready to chow down on yet?

Poor thing was egg bound. An awful way for a bird to die. I had a female cockatial that would get egg bound. I used to put her in warm water and let her soak her bottom, You could tell it felt good to her and she would lay her egg soon after. The farmer is not a very good one not to take care of his hen.

I cracked an egg for a fry-up a few days ago and it contained a double yolk! It got me thinking,can a egg produce two chicks? Anyone know if this is possible?
