If the calf is wild now, may I be the first to inform you that it will NOT get any better, unless this beast is the exception. Our neighbor had some calves born in the summer in the pasture that were "wild"..........and when it came time to get them in in the fall, they could NOT, in any way, shape or form even get close to a couple of those calves. Got everyone else, the moms, etc. Sad to say, they had to "contribute to the food chain"..............but it couldn't be helped.
