Sometimes they lay their eggs one after another. example: If a swan was going to lay 3 eggs, here are the times: 10:30am: one egg 10:35: 2nd egg 10:43: 3rd egg. Sometimes there could be a difference in hours, and sometimes day. It depends, you can't exactly choose a specific answer, it's different for every swan. Hope that helped!
