Why do ducklings become lively after being warmed with their palms?

Ducks are generally not afraid of cold. Generally speaking, the temperature of outdoor air is lower than that in the lake in winter, so ducks stay warmer in water than on land. Ducks often swim in the water, and the temperature in their bodies will rise, which will make them more cold-resistant. At the same time, ducks have a very thick layer of feathers around their bodies to prevent heat loss. According to research, the normal body temperature of ducks is about 42℃, which is 5-6℃ higher than that of people, and it can regulate its own body temperature. The bone marrow in the tibia or tarsal bone of waterfowl has a very low freezing point and will not solidify at a very low temperature. Therefore, even if ducks stand in ice water for a long time, they can keep the liquid flowing on their feet. Ducks are gregarious and aggressive, and the gregarious nature of ducks is established through struggle, which is the pecking order. Male and female ducks have their own dominant relationship and form their own independent pecking order. Generally, the strong will give priority to feeding, drinking and breeding, occupy the highest position in the ducks, and assume the responsibility of defending the group, mediating and limiting the aggressive behavior in the group. However, the feathers of the newborn ducklings are not yet full, and they are afraid of cold when they are cold, but when they are warm, they will be skinned alive and jumped around.

Generally, ducks themselves are more lively.
