Step 4: Preserving
Now, place the box in a cool, dark, dry place and forget about it for a month. The cornmeal will absorb the fluids from the body parts during this time, essentially mummifying them. There should be no strong or bad smells coming from the box during this time.
After a month is up, remove the lid, take the bird parts out and inspect them. They should be dry and stiff, and should not feel moist at all. The exposed flesh shold be dry and hard with bits of cornmeal stuck to it. The parts may smell slightly 'meaty' still - this is normal. As long as there are no rotten smells, they should have been preserved perfectly. If the parts are still flexible, or feel or look moist, they have not completed the dessication process. In this case, put them back in the box and add more cornmeal, and leave for another two weeks.
