If ever a reminder was needed that we are still infants in the farming game, it was delivered earlier this year, when we had four separate groups of animals grazing four different fields. For small part-timers like us, where simplicity is key, this was poor management.

At that stage, we had weaned lambs in one field, their mothers in another, had calves in a sheltered field beside the shed and store bullocks in a different field. When a rotational grazing system is important for growing grass, but nearly half your fields are being very slowly grazed, it becomes very difficult to get a handle on what is going on.
