question for those with young Runner ducks

[stonykill]

My young Fawn and white runners hatched on May 26th. This morning I know I grabbed an egg from my adult Runner Penelope. Tonight at lockup there was a smaller bluish egg in the Runner pool. Same color as Penelope's but smaller. Is there any chance 3.5 month old Runners can lay? I don't recall Penelope missing a day all week. Seems too soon?

It's very unlikely but I don't think it's impossible for one of the younger runners to have started this early.

I've gotten 2 replies on another forum that they have had it happen. Stories...(which I take with a grain of salt) says as young as 18 weeks with good management. But so far 2 people world wide have had eggs from Runners as young as 16 weeks. And I just counted off the weeks on the calender. This is 16 weeks!
