You are right about the banding in the first chicks... R. -- Remember when we used to talk bands? Then lines A B C etc? I know I got a yellow banded male and a green banded female...
Perhaps since there were so few at the start it made sense, and subsequently it didn't. For those that got/had banded birds - you can know which line they came from. Maybe the customer demand for background info got to be pretty significant absorber of the time that they had - Dunno.
but then they started changing the color of the lines and the bands. I think they started mixing the lines together which I have no doubt they will do with the 2 new lines as well.
