I've found that MANY websites recommend to clip, or mention it in passing as something not only natural but completely obvious. Like "How stupid would you be to even think about taming a bird still able to fly??" Difficult to avoid them all... Some have good advices despite the clipping part..Oh my gosh, I didn't even read that part... I must be picking and choosing without even knowing it by 'selective viewing'!
Thanks for pointing that out!
