We have a small, rather cheap coop for 4 chickens. We let them out to free range in our yard almost every day for about an hour. We have pine shavings up in their roosting area and egg box but the floor is just the earth (clay soil which can get muddy when it gets wet). I have no problem cleaning the poop from the upper part of the coop that has the pine shavings, but it so hard to clean the earth and often the poop just blends in with the dirt floor. Please help with suggestions - we tried sand once but it didn't work. I just read about putting gravel in first under the sand to help with drainage. We have not tried that yet. For the winter we were thinking about putting down straw or hay. Any suggestions? Thanks! Also, one more thing - sometimes our eggs are completely clean and sometime they are very dirty. We never know if it is poop on the eggs or dirt from the floor of the run. Is it normal for them to poop in the egg box sometimes?
