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