No problems with laminitis because I watch him carefully and confine him to the dryer pastures near the house when I think he might be getting too much. It corresponds nicely with our pasture lease for cattle grazing. Our neighbor usually brings his cattle in early May and again in August or September. After the cattle leave I turn Patch out for grazing and don't need to feed him hay until snow gets too deep. He lets me know when he needs hay.
We never smell anything from the fermenting cabbage. I heard bubbles escaping this morning! Inoculating it with the juice from the former batch and having everything warm really gave it a jump start.
