I am planning on getting two different breeds of geese from holderreads in the spring. I really want sebastropols, but they are just too expensive....I want one thats friendly and likes attention. I want to try and stay away from the more aggressive breeds. I will be keeping each breed in 4'x12' pen, but during the day they each get a 12'x24' run...is this big enough for a trio? Whats your favorite breed?
