So I became a mother to 4 adorable ducklings back in May. I was suppose to get 2 hens and 2 drakes, but ended up with 3 drakes and 1 hen. There are 2 Rouen's & 2 Cayuga's. All summer long and up until a few weeks ago they have had a small man made pond to swim in and enjoyed it everyday. I had to take it down due to our very cold temperatures as winter approaches and it was freezing everyday. I keep 2 small (10 in.) plastic tubs in their run that I fill with warm water in the a.m. But the ducks get in it and try to take a bath so to speak and swim. I want them to still be able to go for a swim if they like during the winter months. Any advice for cheap options of containers for them? Need something that can be easily cleaned and have water hosed into it. Little off topic, but is it a big deal that I have only the 1 hen with 3 drakes? Should I get more hens this Spring? What is a proper ratio?
