After putting it to practical test on the Iowa State College poultry farm, the Iowa Agricultural Experiment Station recommends the permanent shed roof poultry house described in this bulletin. This house was planned and built by the Poultry and Agricultural Engineering sections of the station for housing 75 or more laying hens kept under Iowa conditions. It has given good results in practical use at the poultry farm and on this basis it is recommended to those who have need of a poultry house of this type.
