The Chicken or the Egg question - revisited

ABC News brought this headline to our attention today:

Anti-cancer chicken eggs developed

With this announcement I thought it was all over. The argument about which came first - the chicken or the egg had finally been settled. It was the egg! Obviously.

Then as I read on I became more and more alarmed as the issue seems to have actually become more and more impenetrable.

"British researchers say they have developed genetically modified chickens that can lay eggs that contain the proteins required to develop anti-cancer drugs."

So . . . the chicken come first?
