I have 3 cats that grew up around chickens and the cats are in more danger than the hens! I cant let the chickens free range until the cats are done eating, if I do the chickens scare the cats away and eat all of the cat food.
I have hens hatch baby chicks outside right next to cats under my deck. They’ve never killed a chick. Getting a cat from a shelter and turning it loose outside is practically guaranteeing problems with chickens. A couple of kittens would be fine from the shelter. It’s not about “saving cats”.I wouldn't suggest adopting a kitten to be a barn cat. The life of a barn cat is a harder one than an indoor cat, and kittens are adoptable to be indoor cats. For barn cats, go to shelters and get the ones that are never going to do well indoors, it saves them from being put down. Some cats are too feral to ever make good housecats but will do fine as barn cats with minimal people interaction.
Baby chicks aren't going to be safe around cats, they're too tempting and too vulnerable to infections from the bacteria in a cat's mouth. Keep the baby chicks out of reach, let the roosters teach the cats to leave the adults alone.
