Last year at the end of the roe rut l was watching a roe just at last light in a stubble field and noticed a fox enter the field, what l observed next was very interesting, the fox ran up to the roe and a game of chasing and running rings around each other started each one taking it in turns to do the running while the other stood, this continued for a short while, there was no aggresion from either side they just looked like they was having fun.
