This is the nurse cow herd at the Heidel Farm. They are a 100% grass fed and organic dairy. Most of their calves are born in the spring and taken right out to pasture with their mothers when they fields are ready for them. In the nurse cow herd, a few cows with excellent mothering instincts are chosen to stay with the calves all summer. They ‘adopt’ the other calves. Currently the ratio is about 1 mother cow to 2 calves. The farmer, Dave Heidel, has found this method to raise the healthiest, heartiest, largest calves he’s ever seen. And he’s been a farmer his whole life. Which is 70 years.
