only problem I could see would be feathers getting in the way. 

 now I’m curious. Lol. 
thats great! I know an awesome vet tech here that didn’t want to do gen practice and is in research now. Lots of options out there. 

My feeling on the issues surrounding caponing would be based primarily on animal welfare. Not sure about elsewhere but here the requirements are constantly changing for so many things. I might look into that, usually CVMA puts out position statements on things like that... lots of food for thought.
