The F1 line worked out well. Kept twenty pullets of the original twenty four hatched. Seventeen of those laid blue, blue/green, olive eggs. Three managed to miss the blue egg gene altogether. The blues and olives were so nice in color (early in their lay cycle) I decided to go both ways so split them into two breeding lines. The F2 blues are just now starting to lay so it's too soon to know much yet. The F2 greens should begin to lay in another two to three weeks. So far, so good.
