rangos little scab

[danone]

hello all, found a little scab on rangos ear. its on the out side floppy part,not on the inner ear. its a little scab that looks fresh then on the other side of the ear it looks a bit dry. my other pig skiddy recently had a fungal infection so i have some surolan at hand which i used on the dry patch on rangos ear, now it could be me being paranoid about fungal. they get on really well apart from the normal teenage rumble strutting and mounting etc so I'm ruling out fighting but it could of been a little get off my back nip maybe ? they are both in the middle of a xeno treatment so I'm also ruling out mites ? also it does not look sore and he did not mind me touching it etc, any thoughts ? thanks.
