Blue is doing really well. In fact, he's thriving! More feathers are coming out and a lot more fluff has appeared. His throat and crop are still pink skin though.
He's eating like a little champion and since his eyes have opened fully has bonded with me. He's up and about most of the day now, sleeps right through the night and is finding his feet. He sits on me and grooms himself after every meal, as well as a good stretch of the wings, legs and neck.
Yep, he's fast becoming a very vocal and loved member of the family.
