Sorry you are having so much trouble, hoping it isn't Mareks, though I have had a few birds with it in the past, it seemed limited to those individuals, so hopefully all the rest thrive. I love blue and blue splash.
Thank you. I really don't think it's Mereks. He injured his leg from a trip or landed wrong from sparring with the black. When I tried to check himover he got away from me and flew then landed very hard on wood floor. He slowly worsened after that.I feel horrid for not having a better hold on him but know he is no longer suffering.
