Well for about 3 months my 6 buff orpington pullets have gone from day olds living in an aquarium on top of the fridge to a XL dog carrier in the carport. Using materials from work(I build portable buildings) I made a 5x4x5 tall metal insulated chicken house. No nest boxes yet, but soon. The run is constructed from 2x2 steel tubing. It is designed to be easily taken apart(We are moving back to the country, hopefully soon). The run door is 1x2 tubing. The run is 5feet tall, 4 feet wide, 8 feet long, covered in chicken wire. Here a a few of the pullets checking out the new living quarters this morning.
