I have a bantam cochin rooster who got into a fight with another rooster a few days ago. His face had some cuts and so I cleaned him up and began treating him with neosporin. The day before yesterday his face started to swell slightly, and now his face, comb, wattles, and ears are very puffy, whitish-yellow and oozing something. I stopped the neosporin because I didn't know if he was having some reaction to it, and so I am wondering how I should treat him. His behavior is normal, and he is eating, drinking, breathing easily, crowing, etc. Normally when he has gotten into fights in the past he has received minor injuries but they have never swelled up before or become infected. What should I do?
