If I may speak out of turn - EE are not a breed, but a mixed breed bird that is created using one blue egg laying parent breed. The offspring "may" lay a blue/green egg, but can also produce shades of brown (from cream to pinkish to plain ol' brown). The fun of EE is the mystery of what they will look like (being mixed breeds they come out a wide variety of colors/patterns, some are bearded, some are clean faced and comb types can vary as well. Just as with the appearances varying, so does production - a lot depends on the parent breeds used in the cross as a bird from higher production breeds will be more likely to produce than those from lower laying parent breeds. The three in our flock average from 4-6 eggs each a week.
