Ginger's injury

When we went to feed and water the creatures this afternoon, Ginger appeared with her beard completely covered with blood. She was not upset about it, so it is hard to tell when the injury happened, but it apparently was recent. She has a 1/2 inch section of her lower lip missing. It is a huge gash. She will not let us touch it to treat it with anything. She is still eating well. I gave her an extra dose of the herbal antibiotics we have available here. Hopefully it won't get infected.
