CLB was my guess based on the body shape and tail. Must have been a barred ancestor in his father since it is so prevalent in him. One of my June EE chicks started chipmunk, changed to barred and the barring slowly changed to lacing, starting at the neck and working back. It will be interesting to see if his offspring, or what percentage of them, have the typical EE muffs, beard and green legs. I don't know much of anything about chicken genetics to even guess. Given his parentage I would think his female offspring will be blue egg layers.
