I've had brown chinese geese twice in my goose keeping days. Both times I enjoyed them...but, my family did not. They tend to be a little on the loud side and the ganders were agressive both times...The second gander I kept was worse than the first...gander #2 even went after me a time or two. My Chinese never really sat hard or got broody.
I now keep Roman Tufted and Sebastapols. Family has no complaints. The geese seem to leave them totally alone, no agressive behavior and they not as loud. I have one Sebbie goose that is broody and sitting on eggs. Two Romans are laying..one of which went broody last year and was so diligent...her eggs were clear last year so, I gave her three goslings from a bator hatch that she adored! Great Mom! The other Roman is laying for the first time this season...not sitting hard/broody - yet. I LOVE my geese!
