I just got my first GCC a little under a month ago, and I've been looking into getting his wings and nails done. I'm not new to birds at all, but I prefer to have someone else do the nail trimmings. Anyways. A pet store in my area told me that you should never trim your own birds nails or wings, as they will never forgive you for it, and will bear a grudge against you forever. I've never heard that before, and I haven't found much on the internet in the way of that idea. Does anyone else believe/know that to be true?
