There's at least one raccoon in the area, I've spotted him a couple of times. But he can't get into the coop (I take their safety
seriously!) and he hasn't been able to sneak up on them in daylight. I did loose one about a year ago to a mink. And I've had an occasional problem with a feral cat in the neighbourhood. Those are part of the inevitable byproduct of allowing them to free range. But at night, they're tucked into their Taj MaHen. And nothing short of an annoyed bear is getting in there. 1/4" wire mesh on all four sides and top, and down into the soil for 24 inches. And a latch on the door that even a raccoon hasn't managed to figure out yet.
More Lion Mountain Keemun.
