⟩ IF I HAVE AN OLD EGG IN THE REFRIGERATOR, DO I HAVE TO WORRY ABOUT IT CONTAINING A DEVELOPING CHICK?
No.A chick will only develop from a fertilized egg. Secondly, if the egg were refrigerated, that would also prevent the development of a chick in a fertilized egg. Eggs must be incubated at about 93 degrees for 21 days to produce a chick.
