Hello, My mother in law wants to raise about 10 ducks. She has put me on the task of building them a home. I have done research and I understand that ducks don't roost and the main purpose of a duck house is to keep them safe from predators. Right now, I am planning a simple 6x8 garden tool shed, made of wood. I figure that if I fill the inside with about 6'' of straw, position the shed right for circulation it should all be taken care of. Is there anything else I am missing? Do the ducks need any special perches, nest boxes or shelves inside the pen? Any info or suggestions help! Thank you!
