I have a 6 month old cockerel polish with really swollen wattles. My guess is frostbite because it has been really cold here in Idaho with record snowfall. I read in another forum to put Neosporin on them but I wanted more advice just in case. I have him now in my garage and he's acting fine, even crowing. Here's a picture of them. He is also very big for his age so the other roster picks on him sometimes so that might be another reason for the swelling if the other roster pecked him and it got infected.
