Ever wondered how bird eggs work? Well, just the man to educate us on this topic is David Attenborough in this 2018 documentary titled "Attenborough's Wonder of Eggs".
Being a naturalist David is passionate about birds and their eggs. They incubate new life protecting them from the elements as well as allowing for breathing; they are strong but the bird can break free from the shell and hatch once ready.
But how is an egg made? Why are they the shape they are? And perhaps most importantly, why lay an egg at all? Piece by piece, from creation to hatching, David reveals the wonder behind these miracles of nature.
