>>33329931>They killed one of my chickensAh yeah that is a financial problem.
Delegate your problems OP. A fence that keeps medium-large dogs out (or in) is easier to make than a catproof fence. Make a donut out of dog-proof fence and keep the dog in the donut and the chickens in the donut hole.
Also dogs are cool, making chicken-protection a reasonable excuse for getting an outdoor dog.
Get a dog suited to your climate, give it a nice house with tons of clean fresh water (can share water with the chickens in my experience).
