We have one pony in a paddock (two other horses in another paddock next door for company - not ours). He's a lovely robust New Forest. We poo pick pretty regularly and he is wormed regularly. How important is it to move him for a few weeks to let the paddock rest? Old lady who lives next to paddock says that we must do this, but I am struggling to find another paddock within walking distance (dd1 goes every day twice a day by herself).
