In Egypt today it is an unfortunate and sad fact that many citizens somehow end up unable to feed their sheep for prolonged periods. Current laws allow others to feed the sheep, but that is rarely adequate. Sheep Pox is an extremely contagious disease coming to sheep that are starving.
Therefore, for the sake of sanitation and humanitarianism, any citizen may euthanize (slaughter) any sheep in a pen that has 0 onions. It is morally not right to allow livestock to starve.
