So what do you call a collection of similar creatures? For most common animals you probably know. Wolves, coyotes and dogs gather in packs. Unless they are newborns, in which case we have a litter.
There are prides of lions and broods of chickens. A gathering of sheep is called a flock. So is a gathering of geese. Unless they are flying, in which case they are called a skein. Or if they are grounded they can be called a gaggle.
