Oh, now I see why people mention pitchforking the shavings. I haven't cleaned out the coop since November-just added shavings and clean up poop board. Getting ready for frigid temps this week and decided to shovel out some old shavings and add new. Surprise! Now I know how they make cement! I really got a work out - the shavings were completely stuck together! Lesson learned. I am keeping my pitch fork near the coop from now on! All clean now, but that was way too much work...
