Young bird allowed to follow wingless fowl (5)
I believe the answer is:
owlet
'young bird' is the definition.
(I've seen this before)
'allowed to follow wingless fowl' is the wordplay.
'allowed' becomes 'let' (I've seen this before).
'to follow' is a charade indicator (letters next to each other).
'wingless' indicates the central letters (the wings or sides of the letters are removed).
The middle letters of 'fowl' are 'ow'.
'let' after 'ow' is 'OWLET'.
(Other definitions for owlet that I've seen before include "Offspring of the wise one?" , "Young nocturnal bird of prey" , "who'll give a hoot?" , "Wise young" , "Young fly-by-night" .)
