I do. But I have my hardware cloth dug in 12" and, just for added insurance, I have a perimeter of heavy 12" concrete pavers. I added when I found rats inside. I never was able to find out how they got in there so once they were dispatched I wanted extra protection.
Happy to say that after 2 years of rats, coyotes, skunks, hawks, etc. we haven't lost a chicken to a predator. And the chickens go up and down freely when it suits them.
