If you provide oyster shell for active layers, and they are good at self regulating, Flock Raiser can be fed their entire life...
I have bothe ducks and chickens, always feed Flock Raiser and I do use Layena occasionally for just layers, but all my birds do much better with the 20% protein...
And yes, Purina Flock Raiser is formulated with the higher Niacin amounts adequate for ducklings... just check the ingredients label against regular chick starter... you can see it's much higher to the top of the list than on the chick starter label...
