I have 2 goals. My first is to create a strain that lays an olive green egg. I now have my barnvelders, welsummers and marans' hen producing their first eggs. Does the olive green egg work on only marans and Americaunas or will a lighter version happen with the barnvelders and welsummers. My second goal is to get a strain of blue laced red that has dark red like the rhode island and light gray on the lacing. I have lilac orpingtons, blue laced reds and barnvelders to do this. I know both of these are going to take years. Does anyone have this type of experience with suggestions that would eliminate wasting time.
