Just a quick question - We just bought a couple of calves that were on a nurse cow. They are eating plenty of grain, hay and out on some pasture. Good healthy little guys. For the time being, they are in our pole barn with some hay, water and are getting some grain. How long is it suggested to keep them in there by themselves to finish the weaning until we let them out with our other guys? These two are about 3 weeks younger than the other 4 we have, so a little smaller, but not a huge size difference really. They just arrived to our place yesterday. Thank you in advance for your advice!
