candidscience: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 formDay 6: Beak begins to formDay 10: Beak begins to hardenDay 15: Scales, claws and beak getting ready to break the shellDay 18: Yolk will enter the body cavity of the developing chickDay 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…..Images source -- source link
