Chicken coops basics include roosts for sleeping, laying boxes, roofing and insulation that maintain a comfortable interior temperature, and flooring that allows for easy cleaning and doesn’t easily break down or warp. A floor that is too hard to clean in an area that is too small for the number of chickens you have is a bit of a recipe for disaster, as there will be a quick buildup of droppings, which leads to more bacteria and also parasites and/or insects, which can make your chickens become ill and even pass away prematurely. Some chicken owners prefer a raised floor, but as rodents and snakes will move under floors, it is advised to raise these enough for chickens to easily fit under, and they will keep the pests under control naturally.
