I found this beauty on Craigslist today. Already sealed up, as the previous owner used it for an aquaponics system. Has a drain already built in, and our garden is on the other side of the fence in the picture. I am going to connect the drain to some PVC, and rig some type of drainage to water the garden. Does anybody have any advice for a ramp? Also, I got some pallets today, and I need to build a duck house. I've browsed the internet, but a lot of them are generic. I'd like some advice from some of our more experienced waterfowl owners. I haven't measured it yet, but my best guess is 5x5, and 3.5 ft tall.
