What to feed my ducks?

[jdaly91215]

I have a group of 18 week old ducks, 4 girls 2 boys, that I've been feeding Mazuri maintenance and southern states waterfowl to. Can I keep them on this and provide oyster shell like people do for chickens? I don't want to put them on layer because I have boys. When do I have to start providing extra calcium or worrying about finding an appropriate food for the group?

What breed? The larger the breed, the later the laying.

My runners started at around 16 week - but they were playing hop on top since about 12 weeks, so that was a clue.

Most folks can set out free choice oyster shell with a flock feed and do fine. Some ducks do seem to need more than that, but I would wait and see if that becomes a concern.
