P.S. If anybody is feeling uneasy about the ethics of the cone. I find that chickens are surprisingly calm when inside the cone, even though they are restrained and hanging upside down. I did not expect that. I've done quite a few now, with the cone, including as favors for friends (who needed the job done), and I've never had a chicken struggle from inside the cone. They go strangely calm once they're in it, so it's less upsetting to the human. Maybe because it's such an unexpected, unnatural position for them - they are more puzzled and confused than anything else!
