I have the same question being invthe same situation. I have six ducks and they make do with their kiddie pool and really appreciate it. I hope to offer them more next spring and dig a small pond for them. Solar is my only option to keep the water moving and filtered. Will probably need something to skim out feathers too. They found my ornamental pond/waterfall and quickly clogged the pump with feathers. As I conduct my research I can post it here. Please do the same. This is my winter project.
