It would probably be a good idea to have a vet look at your heifer. The lesions are likely warts, ringworm is possible too, although you can't usually "pull off scabs to blood". Both of these conditions could make the animal ineligible to be at a show, so it would be a good idea to get them taken care of as soon as possible.
