I support Alex the whole way on this one but the idiot who commented on this is a moron who cares if the chickens are smaller they'll taste better and be healthier for you and the fruit will taste fresh.
your right the chickens sit in there crap and die and contaminate the other chickens.
I believe that gmos are bad they don't know what harm they can do and the chickens grow twice the size they used to in half the time they don't taste the same.
