Praise to the EU. Male chicken shredding has been outlawed since 2022!
Edit: I was pattially wrong about this. The ban is only in effect in some of the members. Namely: Germany, France, Italy Luxemberg and Austria The EU itself is still in the process of deciding on such a law.
As far as I know most get sold to meat farms where they’re raised to about 1 year old with the other meat chickens and then slaughtered for meat. Still far from ideal, but way better than being shredded right after birth.
