I have had chickens heads bitten off through wire. It's not nice
finding a headless body where it has finally collapsed..

I lived on a poultry farm for the first 18 years of my life and I have now
kept chooks for about 30 years of my adult life so I know that chooks can
have their heads bitten off through wire. I've seen it too.

If others haven't had the experieince of seeing that, then they are luckier
than your and I. It doesn't mean that it doesn't happen, just that they
don't know that it happens and can thus remain blissfully ignorant and
sceptical until they do see it.
