I worked for years at a major poultry processor here in Florida, and they hatched all their own eggs. They had their own genetic line for the birds they hatched, BUT those eggs have to be picked up at multiple layer farms and transported to the hatchery. This is how they move them. This doesn't happen often, but it does happen and it's a huge mess. Luckily, I didn't work in the hatchery, I worked collecting blood and meat samples for analyzing by the State of Florida at all our farms before they could be caught for processing.
