Can the swan be outside when it rains?

Swan had better not be outside when it rains. Getting wet is not good for any bird, it will weaken the ability of body temperature regulation and even get sick. As waterfowl, geese like water. They spend one-third of their time in water, but in order to prevent their feathers from getting wet, they will smear the oil secreted by the buttocks glands on their feathers, thus playing a waterproof role.
