Gosh....thats aweful...i have looked a lot at those coop/houses with the trays. I've been wary about them because they have some nice features that i think a coon, fox or coyote could figure out. I have been afraid to order one.i have however thought about getting several because i want to line breed my birds... but pit another enclosure around thst to. Sorry for your loss. I lost 20 chickens i bred and rsised in one month to a possum. Its devastating!
