I agree with varidgerunner that it seems like they are passing legislation ahead of technology. Unless I'm doing the math wrong, it would take 72 hours just to check each egg in one incubator set at the hatchery where I work. We have Jamesway multi-stage incubators and each set has two racks that hold a total of 12,960 eggs. At 20 seconds per egg this would take 72 hours to check each egg in both racks. You can only have the racks outside the incubators for up to 1 hour before the eggs start to die after they begin incubating and there is not enough room inside the machines to check all the eggs with out removing the racks and then removing the individual egg flats to expose them to a laser. The 72 hours that I've calculated doesn't even include the amount of time required to move the racks and flats around to check each egg.
