Sheep and goose heard in African country (6)
I believe the answer is:
uganda
'african country' is the definition.
(country in Africa)
'sheep and goose heard' is the wordplay.
'sheep' becomes 'u' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'and' says to put letters next to each other.
'goose' becomes 'gander' (male goose).
'heard' shows a homophone (sound like).
'gander' sounds like 'ganda'.
'u'+'ganda'='UGANDA'
'in' is the link.
(Other definitions for uganda that I've seen before include "East African republic" , "A gun ad (anag)" , "somewhere in Africa" , "Country W. of Kenya" , "Idi Amin's native land" .)
