Personally I would look to incorporate a wide range of skills with in the drill to include the coach hitting a catch to a group at station 1, once caught the ball is thrown at a stump encouraging station 2 to attack the ball as thrown for a back up/ run out scenario who in turns throw at another stump once fielded, where the keeper is standing to bring the keeper in to play, the keeper then rolls the ball out for station 3 to attack with an under armed pick up and throw back to the coach.
Working with a new group normally needs a fair amount of pro active thinking to adapt the session as it progresses. Have seen many a coach continue with the planned session when it is clearly to hard/easy for the group. Keep it intense and match specific as find women cricketers work better when its a match situation.
