I’ve had chickens for many years, and can confirm this. They have vastly different personalities - some are curious and affectionate, some are shy and much more private. Some are shockingly smart, some are dumb as shit.

Some, you form a bond with. They become pets, friends even. I’m upset for days when they pass. Others - well, at least I’ve given them a good life; I have no issue eating them.

The lines are completely arbitrary. It’s not fair - it’s human nature
