Goat help

[Gideon's girl]

If there's anyone with any ideas, I'd like to hear them. I have a small herd of Pygmy/dwarf goats and one goat has one white horn, which I have always equated with a white hoof on a horse, no big deal. Two weeks ago, a small piece broke off, again no big deal. But now it appears it may be narrower/thinner and have a slightly different curve than the other horn. I'm wondering if I should be supplementing her with something for horns. She is about 8 months old, browsing all day, and getting a small handful of grain twice a day. Thanks in advance for any thoughts.
