I made progress on the older goslings attacking the younger front. I let Jasper and Snow out and brought out the 4 little ones. They actually moved around grazing as a group and Jasper and Snow only gave a few bites to the butts of the younger. It looked more like a "I'm the boss and don't you forget it" type thing. I am hopeful that I will be able to take the divider out of the pen soon.
