I made my chicken a coup out of a large dog house and connected a large dog crate to it with metal frames and chicken wire. It is up against our shed for more shelter from the wind. It also has heavy duty plastic covering the run part for more shelter. I put wood chips and a nesting box in the doghouse. The run is about 4 ft long and 2.5 foot wide. The dog house is about 3 ft square. Is this enough room for 2 chickens and will it be warm enough for a Pennsylvania winter.
