Check this out.
I found it oddly hilarious that scientific research has definitively concluded that a fully-matured chicken must have come first because in order to form the egg shell from which a chicken must develop, it first needs a protien only found in a hen's (female chicken) ovary. The only other option was...just a random egg sitting on the ground waiting to hatch to bring about 'chickendom'?
I also found the expression at the end of the Brian Williams video oddly hilarious as well when he reiterates that the scientists have not figured out where the first chicken came from. Although couched in humor, it shows how people are resistant to accept the plain testimony of Genesis where the uncreated God created all things 'up and running' with full grown adults capable of procreating.

Strange how science proves the premise of scripture.
