Oh I didn't even recognize that as a pea comb, I thought it was too spiky, the only chickens we have with pea combs for comparison are young Easter Egger hens so far
It's not a true pea comb since it has all the spikes... But that's exactly what it looks like when you cross a pea comb with a single comb. The modified pea comb is usually 3 rows of spikes on roosters.
