What does it mean if your budgie has no obvious white iris around his eye and still has some bars on his forehead even though he is about 10 months old and should have these things by 14 weeks?

If your budgie has no obvious white iris and still shows barring on its forehead at 10 months old, it could indicate that he is a younger or possibly a different color mutation that doesn't typically develop the expected iris and barring patterns. In some cases, certain mutations can delay or alter the typical maturation process. It's also possible that he may have health issues affecting his development. Consulting an avian vet can provide clarity and ensure your budgie's well-being.
