Bert and his siblings were cold-heartedly abandoned as chicks. The animal lover, in front of whose door they found themselves, took care of them and nursed them up. Every day they were allowed to make a trip to the lake, together they spent many happy hours. But the older they got, the more the neighbors felt disturbed by them. Seeking help, the animal lover turned to Gut Aiderbichl - Bert and his fellow animals became Aiderbichlers!
