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!

Bad eggs don't hatch into missingno
To determine if a swan's egg will hatch, you can check for signs of development, such as the presence of veins or an embryo inside the egg, which can be seen through a process called candling. Typically, fertile eggs will change in appearance over time, and you may also hear chirping sounds from the egg as the hatching time approaches. However, not all eggs are guaranteed to hatch, as factors like fertility and environmental conditions play significant roles.
