I got an email on this a few days ago. The old man is asking if I could do this... I told him no. Not yet. The higher ups in our operation are looking into this as well. With 40,000+ head in one location alone, they'd like to keep track of the herd health. They're a little different in that their animals are all under roof. Once they leave us, they never have to go outside again. Ours are on open range, more or less. (No more than 100 head per pasture/farm) We're looking into it as well. We have 1000+ head to keep track of daily. If it works, it'll help me a bunch!
