I saw beet pellets for sale at the feed store the other day. We have a heifer we are raising as a family cow. Are these something I would want to throw in with her grain or give her as a treat? Secondly, there was definitely dishonesty in the purchase of her and now that I've been reading more I've noticed the issue of free martin. How common is the incidence of freemartins? I guess I just wouldn't put it past the person I bought her from to have known she was a freemartin when I purchased her.
