Chicken feed for ducks

[percyj]

Can ducklings and ducks have chicken grit? And can laying ducks be fed Chicken Layena? If so, what supplements?

I fed mine chick grit, no problem. It is crushed granite.

Many people feed Layena to their ducks. I don't so let's hear from someone who uses it.

Niacin supplements are a good idea for ducklings on chick starter, since ducklings need three times the niacin chicks do.

Can I feed my adults chick grit too?
