Does anyone have the Farm & Yard Mobile Chicken Coop / Chicken Tractor and has made it work for ducks? I'm thinking some basic modifications to the "house" part would be easy. If this is a quality product, it sure looks like a great option to have around the farm for QT, recovering birds, ducklings, "bad" drakes, etc. We'd love to hear any thoughts. Picture from their website. Thanks in advance.
