Thanks for the pictures.
Last night I had a raccoon try to break in with no luck, so I guess I have it tight enough.
The thing about coons is, they don't have to get in to kill/eat your birds. They can eat 'em right through the wire. If you have coons showing up so soon, sounds as if you may want to set a trap for them? I never had my first encounter with coons at my pen for the first 2-3 years. They can rip a hole in 1" poultry wire too.
