@Folly's place @BantyChooks, others more than welcome.
The picture shows developing black around a cockerel's nostril. The flock has recently been through a bout of mites but this fellow was not heavily infested (if at all). All birds were treated with Permethrin spray and subsequently with sulphur powder; very careful to avoid spraying the head area; mites appear to be gone. Some of my other Chanteclers are also developing black spots as well.
Any suggestions as to what it may be and how I should respond would be appreciated.
