A country's birds (7)
I believe the answer is:
turkeys
'birds' is the definition.
(turkey is a kind of bird)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for turkeys that I've seen before include "The birds for cranberry sauce, or theatre flops" , "Birds with fan-shaped tails" , "Theatre flops or Christmas birds" , "Movie flops" .)
