Partly swapped permanently bleating female, we hear - well done! (4,3,3)
I believe the answer is:
good for you
'well done' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for good for you that I've seen before include "Vegetables are meant to be" , "Well done! Health-giving" , "Generally, fruit and veg is" , "like a healthy steak?" , "wholesome" .)
