I have hung meat like you before, but I always had problems with greyjays and other birds getting caught in the trap.

If the pitch won't come out with gentle brushing and working with your fingers, then leave it alone. Let the buyer deal with it, NAFA even writes that in their fur prep manual. I just brush the hair around it so its not as noticeable. Being that its small and on the belly, the pelt may not even get downgraded.
