February 3 Domestic or Wild Geese?

It's a well-known but perhaps little discussed fact among birders that some birds come in as many color morphs as humans. From Broadway Street I saw 5 different color combinations of geese in the Yaraha River during my ride home. I was at first thrilled to have seen Greater White-Fronted and Snow Geese! Rarities in Wisconsin! (It is also common for amateur birders, like myself, to jump to conclusions on species ID) Further reading, however, leads me to think that these are varieties of domestic geese that are now living life on this open stretch of the Yahara River. Still exciting to see such waterfowl variety in winter.
