Game hunter, maybe one rustling up eggs? (7)
I believe the answer is:
poacher
'game hunter' is the definition.
'poacher' can be an answer for 'hunter' (I have seen 'Illegal hunter ' mean 'poacher' so perhaps 'hunter' could also mean 'poacher'). I am not certain of the 'game' bit.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for poacher that I've seen before include "person who steals food" , "Breakfast chef possibly" , "criminal" , "Gamekeeper's opponent" , "Pilferer" .)
