I have a 4 month male african and a 3 week old african female (i think). I was wondering if I should replace them with older or younger geese. I think waht happened was that the dog and geese didnt grow together and the dog started to attack back after it couldnt take the geese pecking at it. Im not sure if to intoduce the dog to new geese would be easier or just introduce some older geese.
