My husband and I have a Jersey calf that is about 6 months old now. He has seemed to be very healthy up until this past week. I found him two mornings ago bedded down in the barn unable to get up. He is still not able to stand on his own and to heavy for us to lift for very long. He is still eating and drinking though. Seems very lively in that respect. Does anyone know what the problem may be. We are trying to make him as comfortable as possible. Could his legs have seized up because of the cold weather?
