I always wonder when I see one of our goats chowing down on a wild plant that our other goat ignores. Was Abigail fulfilling a pregnancy craving when she spent a few days chowing down on golden ragwort leaves? The plants' green abundance in the brown winter woods suggests that ragwort might be toxic to deer, and data on a related species shows that the leaves are very high in copper. But everyone knows that goats have higher copper requirements than some of their relatives, and Abigail's previous owner didn't administer boluses while Artemesia's previous owner did. I've yet to cross the copper bridge myself, other than providing free-choice minerals and kelp in the coop, so maybe that's why Abigail spent a few days gorging on ragwort...then went off it cold turkey.

Meanwhile, our littler goat always hunts down hog-peanut seeds, even while Abigail is busy chowing down on mountains of honeysuckle leaves a few feet away. Perhaps Artemesia simply likes the nutty flavor, or perhaps she needs more protein to feed her teenage growth spurt.

And then there are the times I catch Abigail scarfing down some dried oak leaves off the forest floor. Could they really have any nutritional value after sitting out in the rain for months? Or does our older goat just need something tough to settle her stomach after gorging on honeysuckle?

After noticing that my own list of favorite vegetables closely matches the list of the most nutritious vegetables, I have to assume that goats and humans alike can tell by taste which natural supplements we need. The trick, I suspect, is to listen to our bodies and learn that just because our eyes want chocolate ice cream, that doesn't mean our stomachs don't want kale and garlic.
