When I built my pens and coops, I was scared to death of my chooks being prey for predators and vowed I would never let them out. Now, everyday I let them out loose in the yard at 7am and go back in the house. I come back out by 7pm to put them back in their pen for the night. I can not believe I am doing this after I was so scared of the idea at first! What are your experiences with free ranging vs keeping them in a pen. Please tell me about your experiences with this.
