Hey Guys
I have had my IRN for about 4 months now and overtime his beak looks like its peeling. I was wondering whether this is normal and might be to do with him growing or whether because of his diet? Have attached photos.
Also I was wondering what colour he is? I think possibly a rainbow as he has green on his wing and a blue body although he has a white head.
Thanks

on most pictures of older irn, the beaks are "peeling" and so it SHOULD be very normal (just like how nails grow and we clip them back, only in beaks, they are rubbed off in layers)
unfortunately i am no expert in mutation colours...
