In my very first batch of blue/barred rocks, I had a gorgeous blue that I thought was a girl, but apparently I missed the head spot, because when the feathers started coming in, they had light barring on them. I didnt want to cull him because he was so pretty, but I couldnt use him. Marina (blueroo) offered to take him, she has some barred girls, and wanted to play around in that direction. She sent me a picture of him today, isnt he amazing??
