Is my brother afraid of cold?

Brother is more afraid of cold, and its cold resistance is not too strong.Usually after winter, its bird cage needs to be placed indoors, but it cannot be hung at the door or window. Although it can be breathable, it is also easy to be blown by cold wind and is not good for its health.At the same time, pay attention to supplementing nutrition and improve the cold resistance of birds.In addition to feeding, the temperature of drinking water should not be low, otherwise it will easily cause it to be diluted.
