This is our first winter with ducks and geese. The geese are tough as can be and are meant to stay on for years as poultry guardians. The ducks probably should have been slaughtered before winter, but got to linger on as they are so fun to watch. Next year I don't think we will winter any ducks unless we can solve this problem.
I give my ducks a heated dog dish to drink and dip their beaks in, and every day I put 3-4" of water in a kiddy pool for them to have a bath. They are happy and vigorous even at -25C (though -30 is too much for any animal to be happy), and flap around the yard and enjoy their baths despite the fact that the water will only be liquid for about 15 minutes.
However every few weeks I lose another duck. I always find them not curled up against the cold but flat on their chest with head on the ground and legs in the air. I noticed these dead ducks always have a huge buildup of frozen dag on their rear end (if this sheep term is the right one for ducks) and I believe it gets to the point where they get anal blockage and die. The mass is often larger than a softball and covers the whole rear end of the duck.
Most ducks stay clean but once it starts to build it seems hard for them to clean this off, as it is frozen on. If the temperature rises to -10 or higher they all get cleaned off, but this winter has had long spells with highs below -20.
How can I help my ducks stay clean in the cold? Note that keeping a water trough open for the likes of my sheep costs ~$100/month in the winter, so a large heated trough for the ducks is out of the question.
