Bird inedible, did you say? (4)
I believe the answer is:
fowl
'bird' is the definition.
(I know that bird can be written as fowl)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for fowl that I've seen before include "Bird, maybe domestic" , "Bird kept for eggs and meat" , "eg Chicken" , "Poultry bird" , "eg hen" .)
