Moose are primarily solitary animals. The only groups you'd see of moose is of a cow with one or more of her calves.

Laying eggs in groups makes them easier to keep warm and safe and increases chance of the hatchlings' survival. Birds keep eggs in nests, where it is necessary to lay eggs in groups to facilitate feeding and care-taking. Fish lay eggs in groups so that predators cannot eat all of the eggs because there are so many in one place at one time.
