I understand all holes/vents/windows will be covered with hardware cloth to help protect my ladies. The coop is going in my back yard which is fenced in but that doesn't mean predators can't get in. Not pictured (I added after) was 2 windows on each side of the coop. There not finished yet so I haven't taken a photo. They are the size of a top of a 5 gallon bucket. I thought that plus and about 20 holes would be enough. I wasn't sure that's why I haven't grilled any holes yet. So I need to make them a lot bigger. What size would you recommend? Thank you so much for all your help!
