Does anybody know what this is caused by? Is she just rubbing her nose on something? I was trying to google what this could be and some people were saying it can be a deficiency of some sort (can't remember what). ??? This girl is currently on pasture in the day and alfalfa at night... She is not on any grain, but probably has loose minerals. She's 4 months bred. We'll be picking her up in 2 weeks.
