Are the ten sisters be afraid of cold?

Ten sisters are not afraid of cold, but it is afraid of wind.Birds have the protection of feathers, and they are basically not afraid of cold, because they have the ability to keep warm, but the wind is not good, so be sure to avoid being blown by the cold wind.Usually, after winter, you can cover the cage of ten sisters with a cage, or add a thermal insulation cushion around, but you cannot completely seal it. You still have to leave some gaps to breathe.
