We have Bonnie & Clyde a pair of Ebdems, they looked fully grown and were bought as a pair but they have not yet mated (as we have seen) and our friend has a younger pair that are at it like rabbits. We love the Geese very much but Clyde is so aggressive with the hens and ducks, we hate having to isolate them but have to consider the rest of our flocks, it is a matter of luck he hasnt caused an injury beyound de-feathering. He runs rings around our cock chuck who vainly tries to defend his gals. Only poultry he backs away from are the Guinea Fowl and they are aggressive with the chucks but not the ducks. Not sure if Clyde sees himself asa human, he adores my wife and nibbles her and tries to mate with her. We expect great things from the Geese come spring. They have access to a small pond in their isolation pen and a huge pond when we isolate the duks (4 runners and 4 Bulgarian mute Ducks). It is horrible to have to isolate them but as sonn as you walk away they are after the chucks and ducks. Has anyone else had probs with Geese aggressive to other fowl?
