Why do eggs crack in the refrigerator?

Eggs can crack in the refrigerator due to temperature fluctuations, which can cause the contents inside the egg to expand and contract. Additionally, if eggs are stored improperly, such as in a crowded space or without proper cushioning, they may bump against other items, leading to cracks. It's also possible for moisture accumulation on the shell to weaken it, increasing the likelihood of cracks. Proper storage and handling can help minimize this risk.
