Well, we're dipping into the mid-teens at night and sometimes near freezing during the day. Which means that soon we'll be freezing even during the day! I've done so much searching, but can't make up my mind. I thought I'd come here and ask you all what heated waterer you'd suggest for my little "flock" of 2 ducks and 1 Embden. I have been just filling and re-filling and re-filling and re-filling a large dog bowl of water every day and it's become the inconvenience. Not that I mind doing it for our feather-babies, but I'd like to find something a little more useful. Please help!
