I tried to and also asked my neighbours if some budgie flew into thier house...i'm going to ask the vet for an appointment to chek if jill is ok.
I didn't established a solid relation to jack as he is not really tamed but something i noticed is he is not curious to me anymore example when i use my phone and showing it to him he really likes it...but now since jill arrived he acts like he is frightened to me too as jill does. I can understand a bit after all it is my fault that gina left him. I will give him time to bond with me again. For now i will leave him like that
