Hi! I am looking for a better pool for our two back yard ducks. one that is deep enough for an Indian runner to get her float on!! the kiddie pool we have is just not deep enough for her and she is totally jealous of the mallard's mad floating skills. If any of you can link me to good ideas/purchases i would appreciate it! We have a relatively small back yard in Dallas... so we aren't on a huge amount of land. They are not too keen on the bathtub! Thanks!
