I agree. How much time and trouble is peace of mind worth? I'm no longer in the States, and I don't have access to facilities that perform these lab services, so I'm 'making-do' with do-it-yourself necropsies when necessary. It's not much different than when I process a bird for the freezer, except that I pay much more attention to the innards to find the answer to 'why?'. It's so hard to diagnose which illness a chick has (while living) since most present about the same way... droopy, saggy, lethargic bird/chick... fussy eater if eating at all, reluctant to drink water (or drinking tons of water), poop runny as birds get rid of excess heat with runny poop too, making it even harder to use 'runny' as a diagnostic tool, you're left to decipher if it's fever that's causing heat, brooding that's causing it, or overall temperature, or an outright symptom of the disease itself (etc), head down, fluffy feathers, standoffishness from the others... you can pretty much add all of those symptoms to any avian illness you can think of. Pretty much why you'll see on the forums folks asking for photos if you have them, and asking specific questions to isolate nuances of an illness.
