Depends on the judge and the show, the county fair I grew up with started as a pretty laid back bucket calf type show but has evolved to a full fledged prospect show. One faimily has done quite well. Over the years bring flush mates, they usually get champion or rescue in at least two of the four divisions........ Last year the judge picked a pretty big calf, that was a beast amd good, to win it, a calf that was too big to ealistically be a project for the same show next year. Other years the judge has kept in mind that the idea of the show was for calves that would come back the next year and gone with smaller calves that were good enough to compete, but the right size to be a project for next year. I also know that the calves are not usually weaned at our fair... Day weaned maybe, but they bring em up and show them the same day..... Quite certain most go back to the cow in the evening, I would be careful weaning, could set him back, might be better off day weaning, work with him then turn him back with mama
