Unlike most birds, why can chickens continuously produce infertile eggs?

So, I guess(?), duck and quail eggs are available (but people actively breed both and would have eggs….) but I know that turkeys and geese have a breeding season. Also, wild birds only lay fertile eggs in season to reproduce.

Chickens have been domesticated for longer than ducks or geese. They have been selectively bred for egg laying, so that they lay a lot more eggs than they would ever need to do in the wild. Domestic ducks and geese also lay more eggs than wild equivalents, but they haven’t had as much time for the extreme genetic change of chickens.
