I love Indian Ringnecks, awesome birds, mine is 4 years old almost and his ring showed up at the age of 2. He is a little grumpy sometimes, and can get very territorial. Mine is green color though and his ringneck is black & orange. Can say few things and many other things that i don't understand. Your birds are lovely, and they will get very pretty at the age of 3. If they get a ring on their neck it means they are males. Careful with your fingers as their bite is really nasty and i have some scars
