Film hen, perhaps (5)
I believe the answer is:
layer
I believe this is a double definition.
'film' is the first definition.
(I've seen this before)
'hen perhaps' is the second definition.
(something that lays)
(Other definitions for layer that I've seen before include "Thickness of material or earth - relay it" , "Early (anag.)" , "Source of eggs" , "Productive chicken" , "course" .)
