Cold weather can lead to frostbite, especially on ducks' feet and, for Muscovy ducks, their facial caruncles. Illness, poor feather condition, and freezing rain increase vulnerability. Ducks unable to access dry bedding or shelter may face hypothermia or mobility issues. Young, sick, or injured ducks are at higher risk and require closer monitoring. Frostbite symptoms include swollen toes, blackened skin, and difficulty walking. Without intervention, these conditions can worsen, potentially leading to permanent damage or death.
