Ooops! Been there, and I remember it well. We had a 'surprise' Welsh/Dorset cross ram (his mother escaped into the field with the ram) who, like his Welsh mountain mother could jump six foot fences at the drop of a hat. He was only 6 months old but managed to serve several ewes in the short time he was in the wrong field. Neighbour, a good friend, not very pleased, but understanding. Sold him to a farmer with lots of open spaces and no fences not long after.
