This nest is a great alternative to the metal nest box. The plastic surface is easy to keep clean and does not get as cold as metal. Amply sized, hen-friendly design features an entrance perch and ventilation holes for fresh air. Space saving modular layout lets you mount the nest vertically or side by side on 16 on-center studs. 16.5” L x 15.88” W x 19.75” H.
The nest box lacks a back wall. Other than that I have no complaint.
