About a week ago one of the calves started limping around, so I checked on it and it appeared to have foot rot. So I gave her a shot and moved the calves to a dry lot instead of the muddy one they were in. In my experience one you treat foot rot it usually improves in 3-4 days. Well this calf has gotten worse, now it wont even put any pressure on its foot. So I'm back to the drawing board. Any suggestions??????
