One of the best materials for a chicken coop floor is plywood. A plywood floor can be raised off the ground to help in keeping the floor and bedding dry. A floor with airflow underneath will shed moisture more quickly than a concrete slab or dirt floor. A raised plywood floor is also a very tight floor that prevents unwanted predators and rodents from entering. If your chicken coop is a storage shed with a plywood floor on runners, use a tight wire mesh instead of wood to close off the underside of the shed to intruders. The wire is better than wood since it allows air to flow under the shed while still closing it off to intruders. Raising the floor in a coop is an inexpensive way to promote the health and safety of the chickens in a wooden chicken coop.
Tip: A plywood floor should be covered with epoxy or a similar material to make cleaning easier.
Food and Water Supply
Last but not least, a well-functioning feeder and drinkers are some of the most important components of the interior of your coop. The feeder and drinkers should be kept away from the roost to prevent chickens from pooping in them while roosting. They can also be suspended off the ground a few inches so that they don’t collect as much bedding when chickens are scratching nearby. Feeders and drinkers should be clean, well-stocked, and easily accessible to your chickens at times. Partially dehydrated or under-fed chickens are much more prone to disease and will be less productive.
