I acknowledge that food is cruel. Plants scream when you cut them, you just can't hear it. There are animals that kill their food by suffocation, drowning, spinal damage, being dismembered, impaling, and worst of all, the trauma of being devoured alive. Nature is cruel, humans are no different. We've just centralized the production and distribution.
All that said, I don't think we should make them live in cruel conditions. Let them go outside and walk around while they grow up before you take a pneumatic hammer to their skulls ffs.
