Stepping back to poop is very normal most ducklings do it.
I think you might want to change the diet though it doesn't sound like the right food for ducklings. Can you tell us what all is in the food your feeding. Grit is something you will want too since they don't have teeth to chew with they use grit to process their feed and the only time you wouldn't need to offer grit is if you were feeding nothing but starter feed for poultry.
That feed is not for ducklings no way they can digest that at a young age. They need a starter /grower or an all flock feed in crumbles. That is not normal poop. Where in the world are you? Do you have feed stores?
