Hey there, I have been a member for a long time but not active. I keep both chickens and ducks, in the same run, and recently built a raised duck pond for my ducks. I've used kiddie pools for years as well as those black plastic things found in feed stores, all did the job but I wanted something different. I wanted something that would drain away from my run, be deep enough for the ducks to really enjoy and also look good at the same time. I did not want anything that would require digging or something put into the ground either. I searched the web everywhere and could not find exactly what it was I wanted so I took several different things I did see and like and and came up with this idea. Using a cast iron tub I bought off FB for $25, some PVC plumbing, a ball valve, and 2x6s I was able to build it for under $100. Its really a very easy project and i have all the details in a video i made on my IG page @liveoaksfarmhouse if interested in building your own. Using the tub slightly elevated allows me to use the existing drain hole to easily and quickly empty it, and using the ball valve outside the tub allows me to very easily and quickly empty the tub with the drain pipe flushing the dirty water out into the field outside the run keeping my run nice and dry. I have no ramp but tree stumps and the ducks have no problem getting in and out on their own. They love sleeping on the ledge as well. I will be adding some river rock along the bottom where the gap is as I put the wood on pavers so it wasn't sitting in the sand.
