What kind of goose am I seeing???

Question

There is a flock of Canadian geese by my house, but there are two oddball geese in the flock. I have been looking all over the internet to try to identify them and can't figure it out. Anyone know what kind of geese these are? Pictures posted here:

Answer 1

One of them looks like a Brown African Goose

Answer 2

The first goose looks almost like a normal domestic goose.

Maybe domestic geese can breed with wild geese to produce strange variations?

I'm pretty sure that here in Australia domestic ducks cross breed sometimes with wild ducks (not sure if the offspring they produce is fertile though).
