Welcome to BYC! One thing I will suggest is putting down a predator apron around the parameter of your coop if suburban dogs (or other predators) can get in your yard. You can use 2' coated welded wire fencing. Attach it to the base of your coop with a nailer/stapler so that you have a 2' fencing laying on the ground around the entire parameter. Use lawn staples to pin it down to the ground. This will discourage any digging under your coop to get to your girls.
