This is my first year with chickens and I am in the process of building their coop. I have an old 10x10 chainlink dog kennel that I plan on using for the run. I was going to build the coop outside of the pen and cut a small hole in the chainlink for the chickens to exit and enter the coop. Any ideas on how to secure the chain link to the coop so no predetors can get in? Some nights I can't get home until well after dark and want to make sure they are safe if the coop is not closed. Has anyone built a similar style coop and run? If so, pictures would be much appreciated.
