Hi there,
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
Cheers
Julio

To all you veterinary histotechs out there:
We got a case submission of a whole 44 week old chicken head and the
write up states "swollen head and dirty ear canals". This is the
first time we have seen this, even the pathologist is stumped. What
part(s) of the head would you gross, and how?
Any feedback welcome!
Thanks!
