Cowboydoc,
Sounds like you have a good strong operation. The amount of acres required to rotational graze cattle in different parts of the country and the various marketing schemes are what make it all so interesting. Your approach of banding together, even as a family related operation is a good idea. I know several producers in Missouri operate that way. Strength in numbers.
Today was nice and somewhat mild here. We'll be starting field work in a couple weeks. You comment about your need to feed stock because of the snow reminded me of what an old fat cattle producer told me one time. He said, "Feeding cattle fescue and expecting daily gain isn't much better than feeding them snowballs."

I read about the tumbleweed hub fencing system in one of the PRFA of BC fact sheets, but am not familiar with the details of the system. I'm a member of the Virginia Forage and Grassland Council (VFGC) and I don't recall anyone here discussing that system. Maybe you can give me a website that outlines the system.
Regarding cherry tree poison, it is hydrocyanic acid and not just tannins. In addition to the dangers of the leaves in the autumn, I thought you might be interested in the following excerpt from the West Virginia Extension Service.
Robert E. Pitts, Veterinarian WVU Extension Service, May 2003, Livestock Management.
…Another consideration in the spring is the weather. Severe storms with high winds may knock down tree limbs.
The leaves of wild cherry trees are one of the most toxic sources for cattle. In the fresh state, the leaves are not toxic. After they begin to wilt, they are a source of hydrocyanic acid, which may cause death within an hour if enough is consumed. Bark and twigs from the cherry tree are also toxic. If the animal is not found dead, early symptoms may include rapid breathing, muscle incoordination, bloat, excitability, and laying down. The blood and mucous membranes of these animals become bright red. If symptoms are observed in time, treatment includes intravenous injections of sodium nitrite and sodium thiosulfate. Sodium thiosulfate may also be given orally after the initial treatment.
