Permissibility of eating machine slaughtered poultry
I own a slaughterhouse for chickens. Can the birds be machine slaughtered and still be lawful to eat?
Scholars unanimously agree that anything that causes the blood to flow and severs the jugular veins is considered a slaughtering tool except for a fingernail, a toenail, or a tooth which is still attached to the body. Slaughtering an animal with a tooth or nail that is still attached to the body is considered asphyxiation.
Based on this, if the case is as mentioned in the question, i.e. that the birds are machine slaughtered, then this manner of slaughtering is permissible and there is no harm in it.
And God Almighty knows best.
