Eggs get to your grocery store in thee easy steps, in a process that only takes about 4-7 days.
The farmer collects the eggs; they are stored in a cooler until they are sent to a grading station. At the grading station the eggs are washed, candled, and weighed. Eggs are refrigerated until they are loaded on the truck that will take them to the grocery store.
