A couple of nights ago we released two roe deer that had both been involved in road traffic accidents. They had been living in different sheds, and had never met. We simply left the doors of the runs open, so the deer could leave when they wished. To our surprise, next morning, both the deer were outside the enclosure where two young hand-reared deer are spending the winter. The deer were all interested in each other, and the young buck, that we had released, followed the older doe. The next night both the released deer ventured into the woods.
