Our Barred Rock chickens have passed their third birthday, and are still churning out some eggs. Not only that, but they continue increasing in magnitude. Here are the USDA grades for eggs:
| Size or Weight Class | Minimum net weight per dozen |
| Jumbo | 30 ounces |
| Extra Large | 27 ounces |
| Large | 24 ounces |
| Medium | 21 ounces |
| Small | 18 ounces |
| Peewee | 15 ounces |
Notice these are per dozen sizes. Therefore I have deduced the per egg sizes. I just give the three largest:
Jumbo–2.5 oz per egg
Extra large–2.25 oz per egg
Large–2 oz per egg
Obviously the grades are divided by increments of .25 oz, which makes perfect sense, but these grades are intended for commercial producers. For home growers who sell a few eggs, I propose a couple of new marketing categories:
Double Extra Jumbo–3 oz per egg
Extra Jumbo–2.75 per egg
The Jumbo is considered a rarity in the commercial market, but two out of a random dozen of our eggs that I weighed were Jumbo eggs, and one was a 2x. This size was not at all unusual:
Using these new size categories could mean a few extra bucks at the farmer’s market this year, for growers of quality eggs. I think we will have a couple of 2x jumbo eggs for breakfast today.
