Here's some pics from my set up. I normally keep from five to twelve chickens, currently have five hens and a rooster. I built the coop myself. There is a 625 sq. ft. pen attached. The coop is on attached 6 x 6 skids and has heavy-duty eye-bolts attached so it can be easily towed to new locations. Not exactly a chicken tractor but we take the fence down and move everything to a new location every couple of years. The pic below is several years old, we had too many chickens at the time and they wiped out the grass. We moved everything soon after.
The old rabbit hutch to the left serves as a place to raise chicks, we buy them when they are a day or two old. It serves double duty as a pen to break broody hens of their broodiness.
The nesting boxes stick out the back.
The food tray and water fount. The water fount sits on a heater base in the winter. It keeps the water liquid down into the single digits. There are three nesting boxes and a storage area on the left for things like heat lamps and small feeders and water founts for the chicks. You can see the roosting areas on the left and right. There are also two diagonal roosting areas up higher on the left for a total of about fourteen feet of roosting space.
A close up of the nesting boxes. Although there are three and they are identical, nearly all hens over the last ten or so years have preferred the one on the right. I've seen three hens trying to lay in there at the same time while the other two boxes stood empty.
I put covers on them in an attempt to make the other nesting boxes more appealing, it didn't work. Now the covers stay rolled up.
I put two glass windows in, one in each side. The openings are covered in galvanized hardware cloth. They are kept down in warrm weather for ventilation.
They are closed up during cold weather.
The chicken door/ramp.
It can be closed up and locked at night.
The two photos above are several years old. The coop and fence have since been moved to a new location and the old chicken door replaced. It was worn out from never being closed. We've never had a problem with predators getting inside the coop at night.
Years ago I put the inside and outside coop lights on a timer to give the hens 15-16 hours of light each day during the late fall and winter months. It made a huge difference. Most of my birds lay an egg a day right through the winter now.
An old oil drum I found at camp. It holds exactly 100 pounds of pellets.
I keep a chart to make sure none of the girls are slacking. Slacking will get you invited to dinner.
The result of all our hard labor.
