Spots on ears

[Ram20]

Some of my sheep have developed spots on the ear. They are small herd knots and maybe some hair loss. They are about half the size of a pencil eraser. First thought parasite's of some type, but not sure. I have posted a pic, but didn't turn out very good. Maybe it will help.

Looks like it could be some sort of external parasite. I've never dealt with any of them so I'm not sure which one it could be. Is it only on the ears though? Any other hair loss on the body?

Only on ears. I figure parasite because one looks like it has rubbed on a post or tree and ear was bleeding a little. Not sure what to use.

What have your temperatures been? Could be damage from the cold.

We have had some 5 degree weather. I dusted them today for parasites and my spray later. Sure can't hurt I guess.

Mine have done this in the winter especially my Targhees.

Noticed today a little hair coming off face just above the nose. May just be weather. Thanks
