Twin bull calves born last Thursday. Calves both up, nursing and appearing to be doing OK. Then on Saturday morning found one that appeared to be a little groggy, weak and not nursing. We milked the mother and he drank, but he seems to be getting weaker. Temp of 102.5. We are doing everything that our vet instructs, but he isn't rallying. He will get up and stand and walk around the barn, but shows no interest in nursing. Late last night he had watery bowel movement. All suggestions are welcome. Sure would hate to loose him.
