I think this is horable! If you are trying to find a way to keep skippash grounded you need to find someone who can give a good wing clip ar try to do it yourself till you figure out what works. It takes lots of practice, but if you work at it you can figure out how to keep them from gaining height. I'm not an animal rights freak, rather believe in treating animals as humanely as possible and meeting them on their level every chance we get. Now I'm not going to do the bad bad people speech, but think about it - we put them in a cage instead of their native habitat, and by doing that we severly limit their freedom even if they are allowed out of the cage alot they should be able to fly to get away from a dog or cat or at least be able to glide a little. So yeah it most cases especially when it is just for convenience sake I do think pinioning is inhumane - not in the since that it causes pain, but I think it would have horrible pgychological effects.
Not trying to tear into you red but that's my opinion.
