If you do decide to make your afghan out of squares or rectangles, it is important that they be the SAME size, since you will be joining them. A common question is how to measure them. There is a Crochet Cabana video tutorial on this subject which can help you figure it out: How to Measure Squares and Rectangles.
Mallards are generalist foragers and will eat a wide variety of food. They donât dive, but dabble to feed, tipping forward in the water to eat seeds and aquatic vegetation. They also roam around on the shore and pick at vegetation and prey on the ground.
There are many kinds of ducks and they live in different environments all over the world. They eat different things in different environmental niches. Sometimes they are grouped as dabbling ducks, diving ducks and sea ducks. There are other groups as well. If you mean domestic ducks, they are mostly descended from mallard ducks. They are omnivores. They eat about 1/3 animal and 2/3 plant matter. The animals they eat are gastropods, invertebrates (including beetles, flies, lepidopterans, dragonflies, and caddisflies), crustaceans, worms and sometimes frogs. They feed by dabbling, grazing and hunting for invertebrates on land and in the water.
