And they do not kill for sport. Or fun. Or trophies. They stockpile for food. When it comes to kill or be killed, only humans can risk killing for sport. Those animals that are lucky enough to expend energy on activities not critical to survival get to enjoy some fun.
Don't know if it strikes anyone else as interesting that so many humans have no problem assigning the motivation of "sport" or "spite" to non-human animals but the thread on chickens feeling love or affection is chalked up to anthropomorphism.
I have had multiple mass slaughters of my flock due to racoons. They 100% kill for fun and do mass slaughters. Every other predator I've had only kills one or two birds and immediately takes the body elsewhere. Meanwhile, racoons kill all my birds and just leaves them there. Not a single head or body taken. I heard the last mass slaughter (didn't realize until the morning what happened) and my chickens did not put up a fight at all so it was not for self defense.
