Turkey’s dangling fold of skin (6)
I believe the answer is:
wattle
(Other definitions for wattle that I've seen before include "Material for fences, roofs etc - it hangs from a turkey's throat" , "Fencing material; acacia" , "------ and daub, primitive wall structure" , "Turkey's dangly bit" , "Material for making fences, roofing etc -- Australian acacia" .)
