How many babies do geese have?

Canada geese will typically lay from 3 to 9 eggs each spring.

after they mate, the female will lay 1 fertilized egg every 1 1/2 days, until she's done laying, and will not sit on the nest to begin incubation until after the last egg has been laid.

then, once the last egg has been laid, she will begin incubation and (barring mishap) all eggs will hatch 25 days later, all on the very same day.
