New duck parent help please!

I will try these things! I think I have an old guinea pig cage they can use as a brooder though they might be a bit too small and fit through the bars

I have used a guinea pig cage before and it worked pretty well for a few weeks.

They grow super fast! Here is my khaki Campbells. One is 4 weeks old and the other is 5 weeks old. You can see how big they get in a short time.
