Question 1: Are all 20 chickens said to be halal by virtue of an analogy that the machine in operation was operated by the Muslim (or kitabi). Like your example of an electric knife in the hand of the slaughterman. For example, if i line up 5 chickens on the ground, and have a muslim hold all five ready to be cut, and my electric knife is long enough to reach all five in 1 stroke are they all halal?
