I’m still puzzling over the door and I’m not even sure gaps are a concern. I may post on the coop building forum... FYI, here are pics of the coop, door, and keets when I had just placed them in the coop. The keet standing tall at the front in the dog cage is one of the keets that was killed - our only Coral blue out of 75+ keets we hatched this year!!! We were so very excited to get a Coral blue!!!
When I added the 150 apron pins last night, I definitely found wavy areas that a snake could have easily fit under. We had a large black rat snake get in our garage and eventually saw it leave through a small hole in the garage wall, maybe 3/4” diameter. I wouldn’t have believed that snake could fit through that hole. Snakes are so very difficult to screen out!
