Thank you!
Unfortunately, my local pet store did not have any duckling feed, but it did have chick starter feed. It has 18% protein, which is hopefully enough, but it was medicated, and there were no unmedicated versions in store, so we'll resort to giving only a few servings at a time so they don't overdose. I do plan on supplementing their diet with mixed greens, vegetables, or whatever else I have available, so they can reach their nutritional intake while hopefully avoiding eating too much medication. I won't be home for a few hours however, so they'll have to subsist on the water and bread we had put until then.
Here's a picture of one of the duckies while we were at the farmers market: the one on the right.
