My vote is still allergies!  Are your baby's ears warm to the touch and red?  Is he rubbing them into the ground at all?  Tino's ears went from just red to scabby, just like the pic you posted, overnight!  I took him to the vet the next morning and sure enough, it was allergies.  I had given both he and his yorkie sister boiled chicken that evening and turns out he was allergic!  I had to keep the scabs moist and give him a baby-dose antihistamine...but it cleared it right up. He was miserable, but at least now we know.
