People are worried about seemingly extraordinary cruelty perpetrated against a cute animal (maceration of young chicks) but basically accept regular, banal cruelty against typical farm animals (the practice of eating farming and eating meat and eggs).
I personally think the cause is at least on balance positive morally for any given male chick, but it’s not so clear to me that it’s moral if this scales to the point that the industry may raise more female chickens to lay eggs with less resources/comfort/etc.
