My 8 month old budgy, mell, has been acting strangly latly. Before she was extremely tame (only with me) and she would respond when I talked to her by coming to the front of cage and tweeting. She came out on to my hand every day for a couple of mins and playful nibbled at my hands, but had never bit me badly. Just over a week ago though she started making squawking sounds, not responding to me, biting badly and will not come on to my hand. The only actual change is that it is White out side the window where it snowed but I don't think that will make any difference.
