indian ringneck feather molt ???

hello, am new here i’ve owned birds for years, yesterday i went to buy an indian ringneck male, weve decided to name him Kiko, he’s missing a lot of feathers on his chest and back. We was told that he was just feathering and that there other ring neck had just finished her heavy molt, I just wanted to know if this was normal, i’ve had my conure and cockatiel for a good long time and have never experienced loss of feathers, Kikos feathers seem to coming through slowly but he’s missing a lot of feathers. He’s just turned 2 years old and has his ring already.
