Sorry, David, but someone a) thinks I am you, and b) doesn't like that the links I included somehow added images that I didn't know how to get rid of. So this is coming to you a day later than I originally sent it -- and without the links to the images, which of course is rather silly.

I'm not sure those are even geese. They remind me of the domestic duck breed called Swedish Blue, though not exactly. If you scroll through these images, you see the breed is highly variable, and some have that bit of white around the eye. What doesn't quite look right, though, is that your birds have no white in the breast, and have white neck rings, which none of these Swedish Blue images show. The all-dark breast is like another domestic duck breed, the Khaki Campbell, and in these images, a few show some hint of the white neck ring also. The white neck ring is of course characteristic of the Mallard, the original ancestor of all these domestic breeds. So my best guess is you have some mixed-breed domestic ducks with a patchwork of traits from the different breeds in their background.
