my calf is in my house do to the cold weather he was premature from too young of a cow i bought that should have been open. He appears to have suffered from scours and hypothermia. fixed the scours and gave him nuflor antibiotic. He seems healthly and growing but his hindfeet seem to have been frostbiten. He does not want to walk and only stands to nurse for a short period of time. WHAT CAN I DO TO HELP HIM THROUGH THIS WITH HIS HINDFEET?
