We Aiderbichlers know this from Yvonne & Co. The longer domesticated animals stay in the forest, the more their primal instincts regress. This was also the case with the camera sheep. Plan A was to make them tired with an anaesthetic cocktail - which failed. Plan B, the one with the tranquillizer gun, was rejected. Then there was Plan C. The Aiderbichlers built a trap and the forest owner himself managed to catch the animals. This was not so easy, as one of the four was always the guard. But at some point, even the guard couldn't resist the food. They became Aiderbichlers and were allowed to stay forever.
