Weighing Eggs

We have a faithful egg customer who asked me what the actual size/weight difference is between pullet eggs and standard chicken eggs. So, I got out a scale and began to weigh them...

My notes from the endeavor: 

I weighed full cartons and divided it into single eggs, then I weighed individual eggs.

After weighing two dozen pullet eggs individually and two dozen chicken eggs individually, I found the average pullet egg is 46-47g (35g lowest, 53g highest, most in the 45-47g range). 

The standard chicken eggs range from 57-63g with 57g and 61g being the two most common weights. We have one chicken who consistently lays 63g eggs (the green one). Coincidentally, she is our most mature hen.

So, if I did my math right, that shows the pullet eggs are about 78% of a regular chicken egg. At least at the age our hens are now. I'm sure the early eggs were slightly smaller. 

Now I need to weigh duck eggs...

While collecting eggs over multiple days, I've noticed a pattern; the ducks tend to lay their eggs right away in the morning along with Dixie, our green egg layer. The pullets tend to lay their eggs later in the day. Coincidence? I'm not sure.
