I believe the answer is:

poussin

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for poussin that I've seen before include "Young chicken for eating - French painter, d. 1665" , "Artist" , "He painted" , "Small chicken; painter" , "17th-century French painter" .)

I've seen this clue in The Telegraph.
