I have goats and sheep, and I also found a new feed store that carries these items. They have a loose mineral mix for goats/sheep and a sweetlix block for goats and sheep. I've been using the mineral tubs, which they like but they don't have salt in them, so I bought salt blocks, and I've seen a few animals lick the salt blocks. The loose would be cheaper and if I got a 50 lbs bag that would last quite awhile. The goats weren't eating the loose free choice, but they recently got the hang of it... so pros and cons on either? I copper bolus the goats, so they get the copper as well as their feed will have some copper too.
