So, I need to know if calves for calf roping competitions in rodeos have to be trained. Would help to know something about the process - when trained (if they are), age at sale, how long they can be used for competitions, etc. Search engines haven't been particularly helpful, but maybe that's just my search skills! I've posted for answers on Reddit, but it made me curious. Anyone got great tips, examples, or, even better, funny stories about doing research?
