This spring I am definitely going to have to redesign the coop door. Everyday I go to close it up and have to rake the shavings away from the door so it will close. See up here in Northern Michigan I have chickens who refuse to go outside but are willing to hang out in the big barn and poop all over my tractor, snowmobile, table saw, work bench, storage boxes, did I miss anything. Well they also play the game with me of hey the door is open lets see if we can rake all the shavings out of the coop and put a big ole pile in front of the door. Then they have a gall to just tilt their heads and look at me when I lock them up at night. All nice cuddled up on their perches doing the "What" look as I'm swearing and raking shavings.
