Grading Eggs for the Heritage Chicken Program

Learning to Grade 500 dozen Heritage Eggs

The grading process is really interesting.  I have two fridges in the grading room which are filled with heritage eggs that are collected by the PRC staff. Both fridges fill up in about a week and they hold about 240 dozen eggs.  So I need to come in and grade several times a week in order to keep up – if I can empty a fridge each time, I am doing well.

I take a flat of 30 eggs to the first conveyor belt. I gently press down on the eggs with a suction machine that hugs and lifts them slightly and then I place them gently on the belt and release the hold with a button. Then I do a quick check for cracks and any visible issues and discard those eggs. The belt moves slowly down and I deposit more eggs until I have four to six flats on the belt.

Next, I move to the candling station. I turn on another lever that allows the eggs to slowly roll onto a second belt and they pass above two very bright lights where I can see into the egg itself. I am looking for blood spots and problems inside the egg and also checking again for hidden cracks. If I am satisfied, they make it to the next station which is quite cool. A machine weighs the eggs and then little padded feet gently kick them down into rows and separate out the peewees.

Once I have graded enough eggs, I stop the conveyor belt and head to the rows. I have previously opened up dozens of fresh, new cartons and I place a nice variety of the eggs in the cartons and begin stacking them into crates that hold 30 dozen eggs.  When that group of eggs is gone, I go back and take more trays out of the fridge, suction more on to the belt, look through the light and carton again. And on I go, for hours.  Once I have filled as many crates as I have time or eggs to fill, I go through bio-security processes (more on this in another post) to safely transport them from the grading facility to the cooler in the ACPPTC  facility where they patiently wait. When it is egg pickup time, I load 100 dozen into the office fridge, refilling as needed and hand out to our Heritage Chicken Project supporters!

What I have learned the hard way about grading eggs:

You do not save time by grading way more than the rows can contain before putting in cartons. There is a perfect point of row containment and then they simply leap to the concrete floor. Sigh.

Make sure the suction holder has released ALL the eggs before you fling it back up. (It is on a spring loaded line that keeps it suspended above the belt when you are not using it.) I am sure your imagination can fill in the rest.

Make sure the lever that stops the eggs from entering the candling area is COMPLETELY off before you head off to carton. Otherwise, those babies just keep coming and coming and coming…

Don’t hold more than two eggs in one hand while you continue to carton with the other. This is just simply a bad idea.

Don’t leave the keys that open the gate so you can transport the graded eggs to the ACPPTC  cooler in the pocket of the coat you left at the changing facility. Sigh.
