Jacob'e Little GiantPaperback - 1987
But then Jacob's father gets involved in an exciting experiment: raising giant Canada geese to help save them from extinction. And it's Jacob's job to take care of them, feeding them and protecting them from predators, even chasing away hunters.
Most of all, Jacob worries about the smallest, frailest gosling. Will it grow like the others? Will it have the strength to fly south when the other birds migrate in fall? Only time --and Jacob's watchful care--will tell.
