I put EE's into two different classes- (1) The so-called "mutts" that are a product of mating a known carrier of the blue egg gene with any other breed to produce more blue or green egg layers and (2) EE's that, like my flock, are chickens that have been bred and culled to be consistent in their traits. Mine lay only blue eggs, have green legs and usually produce slight variations of either silver or red colors. It has taken me 12+ years to achieve this. For this reason I don't consider them mutts. Nightowl505- Those are some really nice colored EE's you have there, please don't be offended when folks refer to them as "mutts".
