I'm splitting a barn up into 3 different pens. One for my geese I will be getting and two for ducks. How high should I make the fence dividers in the barns. The geese will be raised with the ducklings, but they will be seperated as they grow older. Right now I have it planned at 33". Is that high enough to keep the sebastopols from jumping over. These are just pens for night time, they will go out during the day.
