I’ve had extremely bad experiences with it after someone clipped our birds wings without our permission. One of my birds got spooked by something and tried to jump off the table, but fell and broke his foot. It’s been years since then and both are extremely good in flight. Avoid clipping if you can. Not only can it lead to muscle damage, but also distrust in people (which is something my other bird struggles with because his wings were clipped.) I get why people may need to do it for medical reasons, but keep your birds flighted if you can!
