Chickens wattles exploded?

[spencerbaillie]

Hi there. I have a friend who just told me that their chickens wattles started swelling up and then exploded? I've never heard of this nor can I find any info out for them. The chicken has since passed (they culled it) but they are still clueless as to what happened. Any ideas? Thanks!

Swollen wattles can be a sign of a sting, but infectious diseases such as coryza or fowl cholera may also cause swelling and infection. Did the chicken have any other symptoms, such as a bad odor or snotty beak, or coughing? Was the comb dark?
