UPDATE: Went to check the girls and busted two opossums trying to get in, I found the spot he was getting in and it wasn't one I saw, he made it!!! I wired everything up and reinforced the area. Stake out and kill time, little jerkface lit a fire up under me, they came back and they're going to pay!!!! I lost three pullets last night, I didn't hear anything! And of course one of them was my favorite SLW--- so out of the three one missing a head body intact, one everything was eaten but the legs and wings, one was fully intact... So what could it be, I thought my coop was secure but apparently not, please help. My first loss and I'm pretty disheartened.
