I bought 2 parakeets they are young but it seems like its one male (white with many other colors) and a female all yellow the female is taller then the other one and i bought them on Sunday but they are so quite! they don't make no noise at all or anything they don't even move from there perch. Why? I seem them only eat when i hand feed them but i saw the male and the female eat from the food cup yesterday and that was the only time. It feels like i have no parakeets at all they make no noise and the they don't move can someone tell me why?
