Just finished building this cage today. I split my herd into two groups. There are two sows that live upstairs in the 2x3 section and the other three sows live downstairs in the 2x4 section. I haven't finished adding their stuff into the cage and have to figure out how I want to do the hayrack on the upper level for easy access. I just put hay in the corner for now on the upstairs level. I also have to add another water bottle to each level.
