As part of the cooperation entered into with the Swiss Sandgrueb Foundation (Egg near Zurich) in 2019, Gut Aiderbichl assumed responsibility for the lifelong care of a healthy group of 15 Arabian mares. The Sandgrueb Foundation had taken over the stock of an Arabian breeder a few years earlier because she had reached her limits due to age and health reasons, had to give up breeding and wanted to know that the animals were in good hands. Her dam is Maha Choyan. Maschalla is a very sensitive mare who is always up for a bit of fun.
