Got plumage from shelf in empty fold (7)

'got plumage' is the definition.
'fledged' can be an answer for 'got' (fledging is a kind of getting). I am unsure of the 'plumage' bit.

'shelf in empty fold' is the wordplay.
'shelf' becomes 'ledge' (synonyms).
'in' means one lot of letters goes inside another.
'empty' suggests removing the centre.
'fold' with its middle taken out is 'fd'.
'ledge' going into 'fd' is 'FLEDGED'.

'from' is the link.

Can you help me to learn more?
