i am just starting on the chicken voyage. and i am getting ready to move my first chicks into their permanent home, their coop and i am trying to take an ounce of prevention. so i'm getting some goats to run with the chickens, i read somewhere that running goats with chickens helps keep birds away. i'm getting two great pyranees/lab mix puppies to raise in the chicken house. i'm hoping this will help to prevent nightime intruders, that and the pit bull that wanders the grounds at night. the only opening in the coop are near the roof. and i had small wire around that. will this keep the snakes out, and have i forgot anything? and will my plans work?
