So far I am happy with the design of the coop/run and find the many doors allow easy access for cleaning without bending over. I am now working on a 10'x10' run that they can access from this unit.
Materials:
Aluminum - free (from an old pick-up camper we had)
Louvered windows - free (from the camper)
Vents - free (from the camper)
Trim - free (mahogany window casings given to me many years ago)
Ladder and table - free ( plywood siding, mahogany, and cedar all given to me)
Pop door - free (piece of thick plastic I found in the garage, framing was the mahogany)
Interior coop paint - free (Recycle center)
Interior/Exterior primer - free (Recycle center)
Floor covering - free, someone gave me a roll
Posts for run/porch - free (from a garden arch that a tornado took down, wood is naturally resistant to rot and insects)
Stain/Sealer - free (Recycle center)
NRP siding for poop table and lining the frame of the coop - $4.00 (H for H ReStore)
Shingles - $15.00 (ReStore, $5.00 a pack)
Brass hinges - $3.00 (ReStore - 50 cents each)
Roofing felt - $4.00 for a roll (ReStore)
Lower run framing - free (friend tore down a deck)
Cement blocks - 5 were free
Hardware cloth - some in machine shed from years ago, most purchased new
Exterior Paint for Coop - $17.00 (regularly $40.00 a gallon)
Roosting board/poop tray unit - free except 2x4 roosts (cedar and mahogany)
Including the items with a cost noted above, I spent about $250.00 on this coop/run. New items included 2x4s for the interior coop framing, cement blocks, siding, exterior and lath screws, shingle nails, roof sheathing, and latches/locks. When I could I got things on sale or used the 11% rebates at Menards from previous purchases.
Here are some pictures of the next component of the project. Although my flock free ranges all day, I wanted to have a larger run for times I wanted them contained. I built this run out of lumber a friend gave me when they tore out a large deck, thus the beefy construction. The run is 10 x 10 ft and 6.5 ft tall. It is covered with hardware cloth on all sides and the top. Around the bottom edges I laid an apron of chain link fence (given to me by a neighbor). On two sides I also overlaid it with hardware cloth. I have some large rocks I will be placing around the edges as well. Next year I will stain it with a redwood stain I got free at the recycle center.
To connect the run to the coop, I built a raised walkway out of the decking lumber and hardware cloth. I laid aluminum sheets I had left over from the PU camper I took apart and laid on top to provide shade and rain protection. In the picture I moved one of the panels to show the hardware cloth on top. Since there is hardware cloth on all top/bottom/and sides, and both ends of the walkway had doors, it has doubled as a broody box when I had a pullet go broody and I wanted to cool her off. I put water and food in with her and one day in the "box" and she had cooled down and went up to the roost that night. The chair is for the chickens to perch on, there is also a stump and a branch perch in the run. The chair was a reclining lawn chair so it is fairly heavy and doesn't tip when the birds perch on the arms or back. It had cracked in the front of the seat so we no longer used it, but the chickens love it.
This is the door that leads from the run to the walkway. It drops down so doubles as a ramp up to the walkway. There are actually two cross pieces on the "ramp" for footing, just didn't have the second one on at the time the pic was taken.
Below is the pop door that leads to the coop's lower run. It is a nylon cutting board from Walmart. This is viewing it from the top of the walkway. It is open here, the bolt slides through to keep it up.
Here is the door shut. The bolt again is slide in to lock in place. I slip another bolt in at the "handle". Making this pop door was the most stressful part of making this run and walkway because I had to cut into a very secure coop. But the door turned out fine and I was very careful to ensure there were no possible entry points around the framing or door. If an animal were to pull out the bolt and pull the door open. they still do not have access to the door's opening.
This is the pop door that leads to the walkway as seen from inside the run under the coop. At night I close both the pop door in the large run and this pop door.
The cost for this run and walkway was about $120. The majority of that was the hardware cloth. The cutting board was about $9.00 and I had to purchase more lath screws and deck screws to finish this project. I was fortunate to have the lumber and chainlink fence given to me and I had hardware for the pop doors and the main entry door on hand.
