I have my goats on a good custom mineral mix made for my area, well I ran out faster than expected because we turned our two young heifers and one young steer in with the herd. Next thing I know all my minerals are gone. So grabbed a bag of Purina wind rain storm or something like that for winter months and started putting that out for everyone. Oh my! I started with a cup in one feeder to see if anyone ate it. That night it was gone, so gradually increased the amount I put out trying to find the magic number where there is still some left the next day. Well I am now up to half a coffee can for them and like 8 goats a DAY! Does this sound right? I did 1/4 coffee can for two weeks, sometimes once a day sometimes twice, in desperation I jumped up to half a can, this weekend I gave half in the am half in the pm and it was still almost all licked clean. I am happy they are eating so much but a little concerned they are super deficient, the goats also dive into it. They also have a selenium and a cobalt block.
