Yeah Jon, it always seemed odd to me to try and make a poultry operation "natural" when in fact the very process of raising the birds is not natural.  I'm not critical of what you're doing, but the bottom line is you are raising a heck of lot of birds together in one house.  It is not natural and requires some "un-natural" means to make it work.  Let's face it, a bird in its natural state would simply die if it got an infection/virus.  Put that bird in your house and we would have a hell of a lot of birds dieing without extraordinary measures.  Which would these PETA prefer??
