I'm just starting a small coop for 6 chicks. I've read some of the discussions where people say they bury the hardware cloth along the bottom of the run to prevent predators from digging under the run. How do you do that with lawn and hard-pan dirt. I read about someone who used some kind of sheet metal instead of hardware cloth and I thought that would be better, (no bending of the metal like hardware cloth) but where do you get something like that??
