Yolk The egg yolk is the yellow ball in the middle of the egg. It is held in place by stringy things called chalaza e. They let the yolk rotate when the egg is turned. This keeps the gro wing baby bird always on the top of the yolk where it is closest to the warmth of its parent. It can also get the air it needs more easily. The yolk is full of nutrients the baby bird needs to grow. In different types of birds, the yolk makes up more or less of the egg. Some birds are helpless when the y hatch. Their eyes are closed, and they don’t have feathers. They nee d their parents for everything. These birds have eggs with smaller yolk s. Other birds hatch with their eye s open and with feathers.

When an egg hatches, the shell is thinner than it was when it was laid because the chick has used some of the calcium for its skeleton. Eggs must be kept warm for the baby bird to grow and hatch. Most birds keep their eggs warm with their body heat. They transfer the heat to their eggs through a bare patch of skin on their belly, or through their legs, or even their feet! A few birds don’t use body heat to warm their eggs. They bury their eggs in warm volcanic soil or piles of rotting plants that produce heat as they break down. The incubation period is the number of days an egg must be kept warm so that it will hatch. It takes only 11 to 14 days for the American robin to hatch. The royal albatross, a big seabird, takes 80 days to hatch!

Fearfully and Wonderfully Made

Eggs are amazing! Now that you kno w how much care God has put in creating a littl e bird’s egg, look up Psalm 139:14-15. Write you r favorite phrases from these verses in a not ebook or on a notecard. If you like to draw, decorat e the words with colored pencils or markers. The n praise God for how wonderfully God has mad e you!

A hummingbird egg is only 13 x 8 millimeters (0.5 x 0.3 inches). That’s smaller than a mini marshmallow!
