I'll ask again about the toe nails super long should they be clipped?
I would certainly clip the nails, but make sure not to go too short right away. I would recommend using a nail clippers intended for a small dog. Also have a plate nearby with a bit of cornstarch on it. If you clip too far and the nail bleeds, grab a pinch of cornstarch and apply it to the end of the nail and hold the bird for a bit so it clots.
