The short answer is no, at least not until right before you want to use them. Why? The answer to the question is that right before a hen lays an egg, the egg is coated in a “bloom” or cuticle. The egg bloom is a thin coating of protein that covers the entire egg and it acts as an outer barrier and protects the insides from harmful bacteria. It seals the egg and protects the chick from the elements before it hatches.
