thanks for you quick response. we have our room quite warm any way, we have the gas fire on night and day! his feet used to be hot when he was on my hand,but now they are cold or just warm. he's eating ok, and drinking, but when he tries to climb in his cage he seems weak. and when he's sitting on the perch he sometimes looks as though he looses his balance. he used to come to the door very quick, but now he dont want to come out of the cage.he is just doing the odd whistle.does this sound like a lack of confidence? will he get all this back when his wings grow again? or could he be taking it all in, and will start talking again soon.
