Welcome from another newbie in Colorado. We too have some of the same predators. Owls, hawks and coyotes. We saw a couple of Bull Snakes earlier in the year. We turned one of the old cattle sheds in to a chicken coop. Definitely a learning experience. Good luck and have fun.
Thanks! Hope they settle down soon. I am keeping my eye on one, she seems a little worse than the others. She pulls at their feet when they are on the roost.
