Hello and Welcome! I recently got 2 ducks a blue Sweden and white crested I think its called they are sweet and really fun! We created a fenced in run with a roof and a large dog house for their shelter we made the run large enough to hold their pool they are big enough now to enjoy the pool and are in it what seems like all the time its really fun to watch them dive in the water and you can see they are having so much fun! We also made a wide ramp so they can get in and out easily. The shed sounds like a great idea! I have found so much great advice here on keeping ducks
