It is a common misconception that ducks don't require protection from the cold. A duck's beak and feet are highly susceptible to frostbite---whether they are domestic or wild. Ducks living in cooler climates are more at risk of developing frostbite, however it can also occur in warmer regions if they are not provided with adequate shelter and supplemental heat. If ducks have been relocated from a warmer climate and are not yet acclimated, they too are at an increased risk of frostbite.
During early stages of frostbite, ducks' feet may feel cold to the touch and/or show mild redness. As the severity increases, as does the degree of inflammation (redness, swelling and pain), often spreading from the toes into the webs of feet. If left untreated, ducks may develop permanent damage, resulting in dry gangrene and sloughing of the tissues. Advanced stages of frostbite may present as shriveled, deteriorating feet with black tissue. At this stage, ducks often will have difficulty standing and walking, and their feet usually end up getting amputated.
