I too would like to know about breeds. We are preparing land to move into the country and was looking into 1 or 2 guard geese. We would hand raise whatever we got, and then introduce them when they were old enough to our 7 crazy ducks who they will be guarding and living with. I researched and the recommended guard geese were tufted roman, saddleback and chinese tufted roman, but good luck finding any of those anywhere around me! And I have had such horrid experiences with mail order babies that I will never ever do that again.
I have a few farms within driving distance here in Texas (4-5 hours for me) that have geese. So, knowing the best breeds would be helpful.
