Teddy has the same thing -in the same spot. I've also seen it in other seramas. It comes & goes. I thought it came when he was cold & clears up when out in the sunshine. If it was the whole comb, I'd be worried about heart. It could be a serama thing or maybe a circulation issue. Let me know if you find more out.
Hens go broody when you don’t want them to… and won’t go broody when you do.
