thats the little door - with a relatively simple latch. view from inside view from outside I realize it needs quite a bit of cleaning up, so don't worry! The fence is 11' but has no roof and does not go very far into the ground. I live in a very small, suburban town in the California bay area. My main concern is raccoons and hawks, as I had one snatch a bunny a few years ago. How do I make this safer for my ducks??
