I have pegboard floors in the 3 4x6' coops, w/ 15"x45" nest-box and one coop has a Silkie apt off another side the same size as the nest box. I use about 1/2 a bag of pine and then continue to add shredded paper. I shred all our junk mail and any non glossy documents. I don't use news paper any more, it is too flimsy and will bind the shredder. I get an average 3 bags of non glossy paper shreds a month. I like the paper as it decomposes faster than the pine, it can be compost in 6 months even if I don't turn the pile. Only will by 3 bags of pine today, as I have to clean out the babies runs (will attach to the coop when all are finished and they are ready to be outside and am getting enough for a few months.
