Probably this spring mine usually begin to lay the next year after they where hatched around 8 months old
Welcome to BYC @ceazed
It usually doesn't take them long to go broody once they start to lay but if she starts to lay before this frigid temps are over take the eggs she'll keep laying, you don't want her sitting and hatching in cold temperatures. Really hard to keep duckling alive. She'll lay all through spring and summer minus a few rests so you'll have plenty of time for ducklings.
