What should a roost look like. I just figured out that the roost and nest box are not one in the same. Does a roost need to be big enough that they won't fall? We have panaramic windows at about 9 feet up, should we put the roost there or lower. I am amazed at what I have learned about chickens and ducks in the last month. Who ever said you stopped learning when you graduated never experienced children or pets.
