The process of development involves mechanisms at the molecular, cellular and tissue levels to arrive at the complex anatomical and physiological structure of an organism. The study of development can shed light into the processes of many diseases and disorders that afflict people worldwide.

Have You Ever Wondered Where Chickens Come From??

When a hen ovulates, the result is a yolk, which can be fertilized internally by sperm from a rooster.  The yolk, whether it’s fertilized or not, is then covered by egg white and then eggshell before the egg is laid. Stages of chicken development after laying:

Day 3: Nose, legs and wings begin to form

Day 6: Beak begins to form

Day 10:  Beak begins to harden

Day 15: Scales, claws and beak getting ready to break the shell

Day 18: Yolk will enter the body cavity of the developing chick

Day 21: Chick hatches!!

…and word to the wise: The eggs we buy in the grocery store are not fertilized, so although a fertilized egg may pass through the cracks once in a very long while, the usual grocery store egg will not develop a chick…..
