Unhatched bird chicks have on their beaks a little ‘tooth’ which enables them to cut a hole (called pipping) in the shell to gain greater oxygen ahead of breaking out at hatching. This little protuberance either drops off or is reabsorbed by the beak afterwards. You may see it on this Senegal parrot (photo taken by Snowmanradio with permission to share).

Here we have evidence of a creator God, meticulously planning the means by which birds would breathe inside the egg before hatching, whilst also providing them with the means to break out.

Matthew 6: “Therefore I tell you, do not be anxious about your life, what you will eat or what you will drink, nor about your body, what you will put on. Is not life more than food, and the body more than clothing? Look at the birds of the air: they neither sow nor reap nor gather into barns, and yet your heavenly Father feeds them.
