I am thinking about getting a pair of geese. I have two dogs who are great with poultry but I have one that is horrible. I have a small pond and stream and 23 acres for them to roam on. The dogs have an underground fence, will the Geese learn their limiits too so they won't wander near the dogs? When the geese are full grown will they be big enough to defend themselves? The dog isn't a hunter or anything but she "played a little to rough with two of my chickens one day and they were killed. I could always build the geese a pasture but I'd like them to free range if it is possible. I have a few other questions too... What type of housing do they need during the cold winter (NY) and what type of feed should be fed during this time? What type of fencing would be needed to keep the geese in?
