How do you get three chicks and three wolves to the other side of a river on a raft without the chicks getting eating but at least one animal has to be on the raft?

You have to put chick #1 and wolf #1 on, go, and leave chick, keep wolf, and come back. Repeat, with the same wolf until all chicks are gone. Now put two wolves and go over, and bring back all chicks. Then pick up remaining wolf and go over.
