Cook or store chicken (7)
I believe the answer is:
rooster
'chicken' is the definition.
(rooster is a kind of chicken)
'cook or store' is the wordplay.
'cook' indicates an anagram.
'or'+'store'='orstore'
'orstore' is an anagram of 'ROOSTER'.
(Other definitions for rooster that I've seen before include "One crows" , "Chanticleer" , "So retro (anag.)" , "Morning caller" , "Bird that wakes up" .)
