I agree with the comment that we are looking for prolific blue egglayers but strongly disagree with straying from rhe type and color here. The beauty of these birds is that they breed true for type color and egg color. Mixing a bunch of different birds together just for blue eggs seems to defeat the purpose. I think thats already been done... Its called an easter egger.I don't know of a set standard other than being BBS coloring. From the original thread it seemed the intention was specifically for a prolific blue egg layer. I would prefer not to have a specific standard for body type etc because I would prefer to select for production value just like you.
