I have a cockerel app. 20 weeks old. One of his wattles is swollen and thick, but there is no indication of pain if I touch and very gently squeeze it; it's quite firm. I'm thinking maybe he was in a scuffle with one of the girls and has a hematoma, but should I give him antibiotic anyway, just in case? And if so, what would I use? I'll try to get a pic or two, and try to figure out how to post it.
