How often should I clean out the hen house?

A chicken or hen house should be cleaned out weekly at a minimum and, in warmer weather, it should probably be cleaned more frequently to prevent the possibility of disease. Straw or other lining in egg laying boxes should be changed weekly, or whenever you notice something like poop or cracked eggs on the straw. Twice a year, do a really deep clean of the whole house, to scrape off all layers of chicken poop, feathers, dried on food scraps, etc. and make the floor, roosts and egg boxes absolutely clean. If you're using the "deep litter" method, you'll only need to clean twice yearly.
