Immediately following a normal approach and landing; on landing roll noticed objects on runway which were turned out to be a large flock of geese. I thought I would be slowed enough and they would start to move so that with these two factors occurring; there would be no conflict. However; since it was a grass runway; and while not wet; I did not want to apply maximum braking on a 'soft' field and risk a loss of control. Since they did not expedite their departure; I ran through them; striking five with propeller and gear door. I do not think anything other than a reduced geese population could prevent this. I retrospectively thought about if a low approach to inspect first would have been useful to avoid this. But I think this would have positioned me to potentially be flying through a departing flock at high power; higher speed; and low altitude in dark conditions resulting in a much less favorable outcome. I have been flying to this field and have not previously noted flocks of birds on the runway while landing.
BE33 pilot reported multiple bird strikes during landing rollout.
