I have to say, I am really taken back by some of these prices. Paying $60+ for a wing and/or nail clip seems excessive.
I am lucky, in that having been a zookeeper, I was taught how to do both so I can do it for my own bird...and second, Nic Nic would likely let anyone of you all do it to him. He that lad back and very accepting of being handled by others.
When I need to clip his wing, I place him on my lap and lift each wing up, open it and clip what needs to be clipped. Nails are much the same, I usually just file them a couple of nights a week to keep the points off. While he is on my lap, I lift his toes, one at a time and file away.
All birds are different, but if you take your time and introduce it to your bird slowly, I would think they could eventually become accustomed to it.
