While I agree with everyone else, that the older the hen, the larger her eggs will get; egg size is also influenced by breed. Some breeds, like the White Leghorn are bred to lay huge eggs fairly early on. Others, like my Barnevelder, lay closer to a medium sized egg.They will still get larger as the hen ages, but will probably never get quite as large as the Leghorn's eggs. Since EE's are mixed with other breeds, it will depend on the strain you have. Some of my EE's lay huge eggs, while others are on the smaller size.
