We've had this rooster since August and he already had a few tiny black spots on his comb, it was in the middle at the top. After a about a week it developed an open sore which has what I think is something draining from it which drys into a white stain you can see around the sore. The black spots have also spread on one side of his comb and seem to have migrated to the front edge now. We have applied neosporin, but it seems to be getting worse. Do any of you know what this could be and what we can do to get this healed up? My Japanese bantam now has a few small black spots on his comb.
