When do Khacki Campbells start laying

[WendyK]

At what age/number of weeks old do Khacki Campbells start laying eggs? I have 20 week olds and was hoping they'd start laying. Since they aren't laying yet, shoud I be feeding them layer feed and do they still require Brewer's Yeast? Will they always need Brewer's yeast?

Mine started laying at about that time (a little over four months old). Just when you think they are never going to lay an egg, one will appear.
I still give mine a small amount of Brewer's yeast (2 of mine are 1 year and 3 are 10 months old) although I have seen other posts by those who stop giving it to them after they are out of the duckling stage. I figure better safe than sorry.

My Hens of different breeds started laying after 8 months old...
