Or in these guy's case the mineral block. Also i think the guy on the left needs to go to the doc to get checked out. I am interested to see what that looks like out of velvet. I am assuming he got a thorn or branch stuck in there and it created that ball around it.
Unfortunatley i wont make it back up to this farm till the first week in October.. If i get anymore pictures of this guy i will surely add them.. May even a pic of him on the ground =)
