How long does it take for wing feathers to grow?

Hi everyone,my parrot had a crash land today when i let her out for some exerise because some of her flight feathers are new regrowing after a molt how long with this take?she seems fine is having a nap now and preening

6-8 weeks to grow a full feather in a cockatiel but it really does vary between species. Once the bird is molting and lost the clipped feathers the new feather takes I think 10 weeks to grow in completely…
