We got our first goats on Sat. They were purchased thru the barter bourd. We have 2 male and 4 female. Half are full grown. They are the sweetest. They are adjusting to their new home well. Now for the question................. Do I really need a mineral block for them now? They are "pastured" on 3 acres of mixed brush. Mostly arrowwood 25% and raspberry 25% and the remainder a total mix. I went to the feed store and they said to give them a protein block. Is this nessesary? They also didn't try to sell me a salt block. I wanted a salt block but said the protien block is what was needed. So I bought it. But I still think I need the salt block. Is this so? I even mentioned the copper issue.
