I read the post on what minerals to feed, but my questions is what form do the minerals come in? Are they a block? I have a cobalt block out with my goats but nothing else yet. When I got my two does, I was told that when Breezy was fed "goat food" that she got sick. I didn't manage to get any better details, but I think they were reffering to a type of goat grain that they fed, and it sounded like she bloated when she ate it. So I figured I better get some advice before I put out anything other than salt. I am in Canada, so I doubt that brand names of Mineral choices will help me any, but I what should I be asking for when I go to the feed store? If the minerals are in a block form then that's easy to put out, if they are typically in a crumble form then do I put them out free choice?
