could be E. coli+virus ("swallen head syndrome") or fowl cholera (P.
multocida). I would check the nasal cavity (slice the peak
longitudinally) and also the infraorbital sinuses. I am at aloss
regarding the ear discharge. Try a coronal slice of the cranium at the
ear opening. A sharp knife should be enough to do the cutting. If not,
try to decalcified the whole head for a couple of days. Then, decal
(if you have not done it previously) the cut tissue before processing.
By the way, if you have any fresh (non fixed) head, to take a sample
from the exudate and do some microbiology could be tremendously
helpful in these cases.
Hope this helps
