What happens to unsold eggs?

Could you please elaborate on the fate of unsold eggs in the market? Do they simply go to waste, or are there alternative uses or processes in place to ensure they do not go to waste? Are there any environmental or ethical considerations surrounding the disposal of these unsold eggs, and if so, how are they addressed? Furthermore, how do farmers and retailers manage their inventory to minimize the number of unsold eggs, and what strategies do they employ to ensure their products are sold before reaching the point of expiration?
