If you have problems with tape sticking to the feathering on her upper legs, you can line the inside of just the sections of the tape that encircle her legs with a small piece of paper towel.
I used a foam leg brace before to help keep the upper legs apart on a pullet with similar problems. I also had leg hobbles on the lower part of her legs.
I have to say treating her was time-consuming to extreme excess, & some times it was quite painful for her. Tape sometimes chafed her a lot because it was hard to keep designing configurations that didn't cause that--especially as her leg shape & size & movement patterns changed--and it also hurt for her when I at times tried taping hobbles tighter to try to reshape bones (This is not something I now think you should try to do with a chick whose problems have gone on more than 10 or so days at the very most, because deformities are so solidified by that time that any such efforts are bound to bring only unsuccessful results, along with suffering).
I learned much working with her. In any future case like hers, I know I will cull much sooner than I did. However, I had many sweet times with her while caring for her & they were very precious to me.
There is a section on my website called "Foam Leg Brace" with a diagram of one, if you'd want to make one. There are also photos of the pullet wearing the brace, near the bottom of the page.
