This is my first time using straw for anything with my chickens; I recently opened up a bale in my daytime run extension so the chickens could have something to dig in where the snow will actually fall through instead of compacting on top. They think it's the best thing since sliced bread. The thick layer of straw has been working well through the latest storm at keeping the snow falling to the bottom so the chickens always have something dry to walk on and dig in. I've read that straw molds more easily than other things like pine shavings (what I'm using elsewhere in the setup). I don't think the straw I've added will get too gross with the temperatures being as cold as they are forecasted to be for a while, but it will warm up at some point. Should I rake it all out as a precaution when things start melting at a good rate?
