I don't know if I'm posting this properly (never used this before), but I've found that the only time our calves have done this is when they are in pain (ie. broken leg, etc). Sounds weird, but had a calf this spring that was in a lot of pain due to the cow having stepped on his jaw and broken it, and while he was recovering, I gave him Ibuprofin from time to time. Maybe that was a huge "No-no", but it didn't seem to do him any harm (he survived and did well). Good luck.
