Ventilation of the hen house is of key concern. We have designed the floor to be primarily made out of hardware cloth mesh, which breathes well. Additionally it will not rust, is easy to clean and built tough to withstand predators like raccoons, foxes or coyotes. Even when the floor is covered with straw or shavings, it will be able to breathe. Additionally, there will be gaps between the boards we use to construct the hen house and run.
If you live in a colder climate. we are offer a "winter kit" which is a removable wooden platform that covers the wire mesh during the winter. It will mitigate any draft that will be entering the coop and keep the hens warmer.
