According to the store's labels, we tested this recipe with a "fryer," a "young chicken," a "roaster," and a "broiler." Short version: They all work and it's mainly a difference in size and whether or not giblets are included. Longer version: Broilers and fryers are typically smaller than a roaster, however the three can pretty much be used interchangeably. They're all considered "young chickens." If you use a larger chicken, you'll need to keep in mind that it will take longer to cook.
