Hello! I have 8 ducks (2 full grown drakes and 6 3 week old females), I am struggling with making a pond that's big enough for them but not too expensive. I was thinking of making a 5ft×5ft pond for them by digging and putting liner, but am finding problems with how to make or find a pump/filter system that work be able to sustain 8 ducks' poop? Right now the drake's just have a kiddie pool that has been having problems with algae which I would also need some temporary help with dealing with that?
Thank you if you have any suggestions or advice!!
