how long will my ducks lay?

[chickensducks&agoose]

I've got 7 ducks, (1 yr old) mallard, 2 KCs, a pekin and 3 (2 yr old) swedes . I've been getting one egg a day for the past 2 weeks (was getting one or two in the fall), and I wondered how many years ducks lay for? My mallard makes sneaky little nests that go rotten, then the dog finds them, eats them then pukes... so I assume it's either a swede or a KC that's laying now...

They will lay steady for about 3 years. Then their laying will slowly taper off. Those khakis are going to lay the most eggs. You can get over 300 per year from a khaki.
