Do goats eat yellow starthistle?
Yes — safe for goats (unlike horses), best grazed early.
Yellow starthistle infests millions of California acres and is famously toxic to horses (it causes "chewing disease"). Goats and sheep, however, eat it safely — ruminants aren't affected — which makes grazing one of the standard control tools recommended by UC researchers.
Timing drives results: grazing during the bolting-to-early-flower window, before the spiny heads harden and set seed, both removes the plant when it's most palatable and cuts off the seed bank. Multiple years of well-timed grazing steadily shrink an infestation; one random pass mostly annoys it.
For horse-property owners, a goat herd is a particularly tidy answer: it removes the exact plant that threatens the horses, without chemicals in the pasture.
