The idea behind a little bit of yogurt is to get probiotics into their body. This helps them to absorb nutrients. You basically add one teaspoon into their water. Many vitamin/electrolytes contain probiotics. I wasn't sure if you were using a commercial product or not. It does not hurt them. I personally always give my babies a mush for the first 3 days. It prevents choking. Again this does not hurt them either. With greens I hold off for 3 days. Sugar is given for a energy boost, again just small amounts. So overall none of these suggestions hurt your ducklings.
Cleaning you can use warm water. Paper towel dry them well and put them back under the brooder. You can tomorrow give them their first bath. Many use their kitchen sink with just an inch of warm water. I usually use a paint tray, and you will be amazed to see some of them dive almost right away. Never step away when they bath and remove them when they start standing around doing nothing.
