I'm not fond of pinless peepers, but I've needed to use them for certain hens in the past. They do work. One hen needed them all the time, -she was a feather picker even as a chick. Another hen reformed after wearing them for 6 months or so, -her issue had to do with being cooped up too long in the winter.
If you decide to try them, I bought a whole boat load once and would be happy to send some!
