Just the bird to attract an alien? (6)

I believe the answer is:

pullet

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

'just the bird' is the definition.
I can't tell whether this defines the answer.

'attract an alien?' is the wordplay.
'attract' becomes 'pull' ('pull' can be a synonym of 'attract').
'an alien?' becomes 'et' (extra terrestrial).
'pull'+'et'='PULLET'

'to' acts as a link.

Can you help me to learn more?

(Other definitions for pullet that I've seen before include "Domestic hen less than 1 year old" , "A young domestic hen less than one year old" , "Young chicken" , "No high-flyer" , "Chicken under one year old" .)
