You know she should’ve had wing surgery in the first place, when she was a filly. Then she can fly.

She could also possibly have weak wing muscles from a birth defect, so not necessarily a lack of size or magic.

You mean wing transplant? Cause her adult wings were absolutely tiny, nowhere as big as those.

Then again, we never see Scootaloo make any attempt to fly with her adult body. Plus we never saw Bulk Biceps as a foal - he could have been in a similar predicament growing up, being much older than Scootaloo when he first flew (my headcanon for him is that his love of lifting stems from the extensive strength training it took to get him flying).
 
And as for the writers: after “Growing Up is Hard to Do” first aired, there was a tweet confirming the obvious intent behind Scootaloo’s adult form, but including the line “Fans are welcome to interpret things how they like”. I interpret that to mean “We’re trying to have it both ways” — that is, satisfy both the fans that were hoping that she’d eventually fly and the ones who were holding her up as a role model for people with disabilities. Though they could just as easily have done that by letting her get a hang glider or something.

Correct.

Thanks! that was my initial idea, but i couldn’t express it very well in words. ><

There’s actually a real-world surgical procedure that could fix that, and it doesn’t require anything fancier than what Equestria is shown to be capable of:
 
Limb Lengthening Surgery

Except Bulk Biceps can’t fly all that well. Even in “Wonderbolts Academy” he is shown struggling a bit when taking off.

Given the way the show works, her main problem is probably magic. Yes her wings are small, but so are Bulk Biceps, and that thing can fly.

A cute and sweet idea, but to me her problem looked more like underdeveloped wing bones rather than underdeveloped feathers.
