This is the Coopubator.An old incubator made of Redwood that we found online. Cost-$50! Roof is from a barn that was being demolished. Nesting boxes were made of scrap lumber.Perches are driftwood from the beach. Window came out of the trash. Wood chips were free from the local lumber yard and are 8 inches deep. All the inner incubator components were recycled to make a chicken tractor and their run. Feeder is left over 4 inch sewer pipe capped on both ends and cut open on top. Since this was an incubator,there are many vents to be utilized depending on the weather. There is a chicken door but i have no photo yet. See page 2 for more photos.
