Scared to charge a pound for eggs (7,3)
I believe the answer is:
chicken run
'a pound for eggs' is the definition.
(pound in which eggs are produced)
'scared to charge' is the wordplay.
'scared' becomes 'chicken'.
'to charge' becomes 'run'.
'chicken'+'run'='CHICKEN-RUN'
(Other definitions for chicken run that I've seen before include "Where fowls are kept" , "Enclosure for fowls - flight from marginal seats!" , "Enclosure, source of free range eggs" , "Animated film - flight to safe seat" .)
