Update: The vet said she has pneumonia. Ya'll were right - I didn't realize that you wouldn't HEAR the crackling sounds when you listened to them breathe. He gave her Nuflor, Banamine, and an intra-nasal IBR - even though she has already had her shots he said the IBR will illicit an immune response and help her body kick the infection. He send me home with a shot of Nuflor and showed me how to give a shot in the vein so I will try another shot of Banamine also on Monday (tonight) Thanks all for the help!
