Answers: The first approach should be to locate the problem by isolating parts of the system one at a time.
Begin by detaching the duct from the smelliest vent. It will hold to be detached in the crawl space. Block stale the hole that is moved out after you detach the metal pipe or flexible duct. Turn the heat on and see if the odor stops. If it stops remove the detached ductwork and inspect it for alien critters.
If it doesn't stop, your problem may be contained by the furnace itself. In fact, it may be inside of the fundamental blower assembly itself. I have regularly found dead mice within the blowers. They make a home within the blower during the summer months and then, when the furnace starts operating again within the fall, they are kill by the spinning squirrel cage.
A competent HVAC tech should know how to locate the problem within 1-3 hours. It might be worth it to hire it done. Good luck.
Your steam exchanger may be bad if you hold a gas furnace?
