I was talking with a friend the other day about some random stuff, and somehow goats and minerals came up. I mentioned I was planning to try the individual loose minerals, and said something about goats (and other animals) supposedly being pretty good about taking the amounts they need of each mineral when they have access to them all separately. She reminded me that she once had a goat that broke into her chicken feed storage shed and ate a bunch of layer feed and died. I think most herbivorous animals will tend to overeat grain foods to the point of sickness or even death. But they seem to handle minerals very differently. Why is that? How come when I put loose minerals out, my goats will take just a little and leave the rest, but if a goat gets into your grain storage, they’ll kill themselves eating grain?
