I've only ever known one duck who would poop on command (Her name is Skeeter, and she's a 9 year old house duck!) she still poops whenever, but she can go on command when her daddy tells her too. I think there's a video on youtube.
As for diapers, they really are only good for indoor use, as they can get pretty dirty on the outside. From someone who diapers her ducks, I don't ever diaper them over night or for long stints. I only let them wear their diaps for maybe 2-4 hours at a time before changing them. Some people do diaper them over night, but you'd have to take away food/water for the evening and you'd still have a mess in the diaper to clean.
For my duckies, I made them a sleeping pen out of corrugated plastic and duct tape. It wipes clean and I put pelleted pine bedding in it. With four ducks, I change the bedding once a week. That way they can poop at will. You may want to think about making them a little sleeper pen out of corrugated plastic inside of your coop to keep the mess down.
I made my sleep pen for about $60 worth of supplies, and a night of cutting/taping. It's really easy to cut and duct tape holds it together nicely. My old one evern had a little door.
