I designed and built it myself. It still needs paint and shingles. There is no exterior egg box as it is in Anchorage AK. and I am thinking the eggs are less likely to freeze if they are in the main room. They are having a tough time with the ladder/slide but I put some velcro tape on it for traction and it has helped. Ventilation is 2" by 4' along the roof line front and back. They will have free run of the yard everyday since I work at home. And it is portable. Big plus. During the winter I can move it closer to our backdoor to run an extension cord for a light bulb.
