Are my IRN's feathers in a bad condition?

[BirdieOwner]

Hi there, about a week ago I ended up with a rescue IRN and he is the cutest little thing. He loves cuddling up to my partner and I, and he is quite chirpy, giving us a squawk now and then too
I am just a bit concerned, because I don't think his wings are looking as healthy as they should be. He is about 5 weeks old now, and we have been feeding him formula which we were recommended and I don't think that his enclosure is too small for him either.
Please could someone advise how you think his feathers are looking and recommend what i can do to ensure that my new feathered friend is healthy and happy.
Thank you.

He is going thru his first molt, shedding baby feathers and growing in his adult ones. Entirely normal.
