3 days ago we got 2 baby Ringneck Parrots. They are very active. But 1 day after getting them I noticed that their feet be cold and their body would start shivering when I am around. At first I thought they were scared but when i am around they will jump out of there box to come on my hand and they don't want to get off. their body temperature is normal though? But their activeness just increases day by day. I am really worried about their feet. Why is this happening? Even the room is very warm.
