I think it's funny. Dehorning, trimming feet, clipping hair, fitting, all are done to change the looks, improve them for the show ring. Is it considered unethical because it's not COMMON practice for the person that thinks it's unethical? Are only the things that have been done for a long time ethical, or just what you have done or know how to do? Personally it just sounds like way more work and cost than I would want to put into a calf my kids showing for just 1 year. Maybe next time I would just buy a steer that is a little better on those back legs, my limited experience, they swell because the suckers are bred like that. Show one that is Sounder constructed and you don't have to worry about it. I wouldn't worry about it, try to get a better one next year
