Not sure what it's called, but I think it is a mix between a single and ????? whatever breed is in his ansestery that gives him dark skin.
Recently read that continued crossing of rose comb to single for several generations can lead to rose combs that look very different than typical. Some pictures showed combs somewhat similar to his, IIRC.
Normally rose comb crossed to single comb produces rose combs that look more or less like the usual rose combs. In some lines you cannot visually tell which rose combed birds are single comb carriers. For some reason rose comb loses degrees of its 'dominance' if continually bred to single for multiple generations- they start to look more like singles but still 'funky' enough to see they aren't singles.
Wish I could have gotten some barred eggs for Christmas.
