I try to tag all my calves on day one, (saves a race on day three). I have had two heifers with a bloody ear after tagging. I try to get in between the webs in the center of the ear. Just wondering if I am messing up, if it's serious (it looks like quite a bit of blood), or if it just happens that you hit a vein, and it's no biggie. Both of them were moon face babies too, if that matters. I put powdered alum on the ears to stop the blood. Advice?
