I've been taking care of two calves. One, which came from our cattle in March, and another we bought towards the beginning of May. The new calf we got now has some bald spots forming around his ears. I am no longer allowed to go into the pasture with them because we think he has ringworm. I have been applying iodine spray to his ears as best as I can (Since I am not allowed in there). I find it weird though because it doesn't look like the other calf is getting anything on him and I read it is very contagious. Do you guys think it is ringworm on his ears or could this just be warts? Below are a few pictures. If it is ringworm, do you guys know a better way I could be applying the iodine?
