We are tupping for the first time too. Our ewes had a mineral drench 3 weeks prior to ram going in, 2 weeks of good grass and gave their feet a once over too. Wormed and fluked when we bought them in August. The ram went in last Saturday, they are out on grassy stubble now as all the good grass was making them look rather round, but they have a handful of cake every morning to keep them tame and ad lib good quality hay which they are picking at as and when.
