Draw extremely elegant fowl (6)
I believe the answer is:
pullet
'fowl' is the definition.
(I know that pullet is a type of biddy)
'draw extremely elegant' is the wordplay.
'draw' becomes 'pull' (pulling is a kind of drawing).
'extremely' means to remove the middle letters (only the extremes of the word are used).
'elegant' with its middle taken out is 'et'.
'pull'+'et'='PULLET'
(Other definitions for pullet that I've seen before include "Chicken under one year old" , "Young chicken" , "A young domestic hen less than one year old" , "Young domestic fowl" , "No high-flyer" .)
