I'm bottle feeding a 13 week old Charolais calf, the weaker of twins. She's had several infections, partly my fault, as I'm new to this and didn't realize need for sanitation. Also turned out allergic to soy-based replacement milk, became extremely weak before I found a vet who diagnosed. Now she's getting raw, whole milk from the dairy. No obvious pain, gaining weight, appears contented. Spends almost all day lying down, however. Gets up when I bring milk, moves very stiffly, like a little old man. Lies back down almost immediately. She's been two weeks now on good milk. Also calf starter fed with a spoon. Will she regain strength, start moving normally? Shall I try to make her walk around? Or am I fighting a losing battle?
