I thought that too. Its what Chooksman calls an "m" right? I will keep him as a backup to cockerel #1 but may not use him for breeding.
That Little Peddler cockerel that sired one of your cockerels has a comb near identical to my cockerel #1. Maybe that's his father as well.
here what I call the M .
the one in the front of the photo has 2 extra dents on the 2 nd point ( giving it Everest mountain Shape )
the one on the far back has a M on the start of his comb. the first and second points are fused together forming a M .we can see it on the shade on the wall .
