    My son is doing a 4-H project for egg-layers chickens. We are trying to find out what the proper way is to determine the egg size (small, medium, large, extra-large, jumbo, etc...) I know there are scales out their, but they must be based soley on weight. Is that the only method (shape is not considered)? If it is only by the weight, we already have scales that can weigh in these small weight ranges, so we would need to know the breakpoints that determine the size.

    Any help would be appreciated.

    Try this USDA egg grading manual. There is some stuff at the end with scales and grades.

    I copied this from a site, I don't remember which one.

    Jumbo 30 oz.
    Extra large. 27 oz.
    Large 24 oz.
    Medium 21 oz
    Small 18 oz
    Pee Wee 15 oz.

    That is the total weight of 12 (1 doz) eggs.

    Thank you both. The USDA guide was very informative. Thanks for the source. My son will have some extra reading to do, but that guide is nice as it also covers the grading process as well.

    Again thank you both!

    Miss Prissy that egg info is pretty good. Is it ok if I save it to my computer?
