The warm weather is over for us. I brought Bootstrap back to the barn and put him in a cage with lots of straw. He just was not strong enough to deal with the cruelty of the rest of the chickens. I put him back in the goat/chicken shed and they ran him out, got him down and were trying to kill him when I rescued him. It wasn't only the roosters that attacked him but also the hens.
If you listen to those who say that humans are the only animal that kills for sport or that humans are more cruel than any other species, you can pretty well bet that they have not had much animal experience.
Dogs, Coyotes, Wolves and big Cats with go into a pen with animals that have no way of escape and kill everything there and not eat anything. The excuse that they are given is that they are teaching their young to kill, but that doesn't hold true when it is just one dog, coyote or wolf.
I have heard of a pen full of pigs being killed by a pack of adult dogs with nothing being eaten. The same thing happened to several Alpacas that I read about and I know of goats being attacked and severely injured by well fed neighborhood dogs.
Chickens have no compassion, they simply eliminate the weakest among them. A hen will peck another hen's chicks to death for no good reason.
Goats will injure each other with or without horns. Many does miscarry after being butted hard by another doe. A doe with newborn kids can be horribly vicious to another doe's newborn kids even injuring or killing them.
Horses are brutal to each other. We had a mare who was close to foaling kick another mare's newborn foal as hard as she could, the poor little guy went rolling head over heels but somehow was not injured. I even saw a friend's mare kick her own young foal after biting it several times, she kicked her so hard that it was a miracle that she didn't have broken bones, just because she tried to eat some grain with her mother.
If you are still not convinced that animals can be cruel, just watch your kitty cat with a mouse, bird, chipmunk, baby rabbit or squirrel. They love to torture before the kill.
