I am betting that it is only frostbite. Someone recently in the last 2 weeks had an idenitcal case of frostbite on comb and huge swollen wattles. Their vet ended up draining the wattles of a lot of clear fluid which relieved his pain. I wish I could post a link to that thread for you to read. I have an Apple computer now, and cannot seem to post links.
	
		
			
		
		
	
				
			
	
 I’m so happy your boy is going to be ok.
