However, use of these plugs without a transformer or voltage converter can result in fireworks. The voltage in Europe is twice that of the voltage in the United States, and while many electronics are designed to adapt to voltage changes, it is crucial to check. If the device is not capable of handling 220 volts of electricity, it will fail.
By the time the ducklings are 3-5 weeks old, weather-dependent, they can spend warm, sunny days outside, carefully supervised and protected from predators. Until the ducks are fully feathered around 7-9 weeks old, they have trouble regulating their body temperature and need heat.
Goslings can be placed outdoors at 2 weeks of age weather permitting. Waterfowl need shade and cannot tolerate chilling rains until they are well feathered on there backs. When ducks or geese reach 5 to 8 weeks of age they need shelter only during extreme weather conditions. Water for swimming isn't necessary for ducks.
