Is it possible to have 2 or more varieties of geese living in harmony on the same property while not being separated? We have a pair of Pilgrim goslings and 2 female Sebastopols. Next year I am thinking of getting another pair Sebastopols and then adding either a pair of American Buffs or Pomeranians. I want them to get along but I am also assuming that they would have to be separated before breeding season to keep the lines pure. After that will they get along or will I have to continually keep them separate?
