I started a new thread for frozen feet since it affects all fowl, not just ducks. In my experience things that cause frozen feet include...
Extremely cold weather (duhhh!)
Metal perches
Thin or sharp edged perches
Dehydration
Wet feet
I would like to particularly address dehydration. It is extremely important your animals are well hydrated in the winter. I cannot emphasize this enough. Dehydration causes the body cells to become flaccid and more to freezing. Frozen cells die. They do not recover. Good hydration promotes good circulation and better resistance to freezing.
Things that help prevent frozen feet...
Heated water dispensers so the birds have access to water at all times.
Flat perches
Birds moving around and encouraging circulation to the feet.
Deep dry bedding
I have not had good luck treating birds with frozen solid feet. They usually rot and drop off. I put my birds down instead of letting them linger. I had one goose who got frozen feet a couple years ago. I brought her in the house and warmed her feet up slowly. They regained some of their color and became flexible again. However, it was clear they were permanently injured. She walked more slowly than the others, then faded and died that spring.
Can any one else contribute their experiences?
