I'm new to chicken keeping. Currently purchased a good, sturdy coop for my 4 chickens. They are still only 2 weeks old so it will be some time before they are outside, but I like to be very prepared. I need advice from you all regarding the best predator proofing methods for their fenced in enclosure, which the coop will be in. I have read about hardware cloth, sunken cement blocks, and electric fencing. What methods seem to be most effective? I also plan on providing a top to the fenced in area to keep birds of prey out. Thank you in advance!
