The artist Erwin Wurm and his wife Elise Mougin are fascinated by the Hungarian Zackel sheep breed and want to contribute to the preservation of these wonderful animals. Zackel sheep are one of the animal breeds threatened with extinction. For this reason, they keep a small herd on their property and lovingly look after them themselves. However, the herd became too large to care for adequately, so they turned to Gut Aiderbichl and asked for help for some of their protégés.
