Hi guys! My budgie cooper is 8 months old and over the past two weeks we've noticed that his cere has got this dry flaky skin on it. Does this look abnormal? He was on a seed only diet but we are currently transitioning to pellets. His behaviour has been completely normal and he hasn't been scratching his beak, but has been scratching his head on the bars of his cage as he's at the end of a moult. If you guys need any more info please let me know!
