Egg numbered 16 is the 4th to hatch today. It is an Olive Egger. If it's a girl she will lay olive colored eggs. In this video you can see how the chick pecks a ring around the egg until she can push her body straight and hatch out. You can see how very tired she is from her work. If you watch carefully you will see bits of shell pop off as she uses her egg tooth from the inside poking through the membrane and the shell. Her pecking action surprises Lilly, the chick resting next to her egg. It is such an amazing feat.
