I've got three 8 week old duckies, who are my first ones, and the last couple days I've noticed lots of loose feathers everywhere. It's like they've turned into shedding cats. They are collecting in the corners of their house and pen and pretty much everywhere they hang out. Is this molting? What should I be expecting? Will they shed all of their feathers? They don't look like they are going bald by any means, they are still sleek and pretty, but every time they rub their bellies, they lose more feathers!
