First, the Eggs Incubate.
When eggs arrive at the hatchery, they are labeled and placed together according to their age and by what farm the eggs came from. This ensures traceability so companies know exactly where the eggs came from, and when. These shelves are then put into large incubators, which look like huge refrigerators, but they actually keep the eggs warm at a particular temperature range and in the correct humidity, with a turning mechanism to make sure the eggs are evenly heated and the embryo won’t stick to the side of the shell.
After 21 days, the eggs are placed in hatching trays and the chicks begin to hatch.
