I would love to make a biggber pond, we have just bought a new pump so we can now pump the water out each week and water the surrounding plants, all the chickens and ducks love that and the ducks get clean pond, then I leave the hose to fill it, I now have to attatch the hose to the shower room tap as the garage tap is no good (knackered!) A big pond would be great and any plants other than shrubs and trees, get destroyed by the hens and ducks!!
