Now that is one deep infection alright. I agree, it looks inflamed up to about the mid point between his eye and nares. The spikes are definitely swollen. I suspect that the infection is all the way down in there and the comb deformity is the result of growing up with the infection. He probably got the infection as a young cockerel and because of it, the comb didn't grow in right, basically making a better "home" for the infection by growing around it. He's still young, and winter hasn't really started to stress out the birds, his body is likely in a balance with the infection. I would fear that any stress would allow it to spread to the blood which would be bad. An injectable antibiotic would be warranted in this case, and I'm one who rarely recommends it. His comb in the middle should largely be about the same width from front to back along the top. At this point, I personally would dub him, but that is up to you, and it is going to be tricky with the width of the comb due to the inflammation. I would not be surprised if there is a pus core in there.
