Who owns a pair? Are they nice? I have 4 ducks, but am thinking of getting a pair of geese. What's the difference of owning geese compared to ducks? Will they leave the ducks/chickens alone? Do they need a seperate coop or can they sleep with my ducks??? Any advice on raising geese would be great! The pair I am looking at our adults already will this make it harder for them to accept the other birds?
