Help with new ducklings

I posted my questions in Other Pets & Livestock by mistake. Would y'all mind going there and helping me with getting started? Thread subject is "Questions for you duck people". Thank you so much. I'm getting two 1-week old Indian Runner ducklings tomorrow! I only know how to brood chicks although I assume it's similar. Do any of you have Indian Runner ducks?? If so, what are they like?
