Justin p, I did the lattice too thinking raccoons were my only actual threat but unfortunately my 11 yr old ran to the coop as she does every morning to see the carnage but I too have put heavy wire mesh over my windows even tho I haven't opened them yet as its still a lil cool here at night. I'm obsessed w/ keeping those dang weasels away lol. My coop is so sealed now u can't see daylight at all w the door closed.... Take that u awful weasels!!! ;-)
