I love using my  copper coated steal  and in all the photos I have looked at of geese the  bottom feathers are a  different color than the rest of the bird . I have some trimming to do  on the  copper wire and a  bit more wire to  add and I still have some grinding and polishing to do. once he is  complete I think I shall mount him on a large rock.  The underside was the frame base in which I started to build up to  make the  shape. The folks who have seen the goose in person like to see the underside. I have been hesitate in showing the underside as it is such a mess!
