Twelve inches of deep litter str:/aw, leaves, and chicken and guinea poop in a 6 by 8 foot coop. Boy was that fun! Still this is the first big muck-out since the coop was finished last summer. Was a little difficult scraping around the edges since the guineas have been hiding eggs along 2 sides. In fact every time I took a break a bunch of them would run in and move thing around then panic and run back out when I got back to work. I think they appreciate the new straw they can bury their eggs in now though. At least they'd better!
