For my new coop I'm building I've got the nest/egg box located on the outside of the coop with an exterior lid/door to gather the eggs. I'd like to hear what kind of latch others use to prevent raccoons from gaining access to the coop through the egg box. Thanks one other question: I'm planning on burying wire mesh about 6 inches under the dirt floor of the run. Would I be safe to use 1 inch by 2 inch or maybe even 2 inch x 4 inch welded wire mesh? Again, thanks.
