We have three bottle calves, one of them was sickly but i think he was just constipated as he is much better now. I was told by our 4-h dairy leader to keep them penned up for at least a month in the barn, as he did't want them eating too much grass. I have a great pasture with lots of sunshine and shade, and i feel really bad about keeping them locked up in stalls all day. How could not getting excersize and sunshine be good for them?? I want to put them out there of a morning after thier feedings and bring them back in at night. He says they will stop drinking thier milk and eating thier starter if i do. What do you think?
