Build an Affordable, Portable and Predator-Proof Chicken Coop

Mobile Chicken Coop

A portable coop allows you to move your chickens to new “pasture” daily. Compared with industrial eggs, eggs from hens allowed to feed on pasture contain four times more vitamin D, three times more vitamin E and seven times more beta carotene.


One of the biggest challenges in keeping chickens is figuring out how to build a chicken coop and pen that will allow your birds to forage while also keeping them safe from predators. Letting the birds roam and consume a diverse diet results in eggs and meat with terrific flavor and nutrition. The downside of allowing chickens to free-range is that predators will almost always discover your flock and kill some birds. Sometimes you may lose just one bird; other times you’ll experience heavy losses in just one attack. Even in urban areas, foxes, raccoons and hawks can kill your chickens, and roaming dogs can be a problem in urban and rural areas.

Portable chicken coops (also called “pasture pens”) are a good solution, especially if you keep only a few hens. You can keep your birds inside a movable chicken coop that has an open bottom so the birds can feed on grass and insects. Each day, move the pen onto a fresh section of your lawn, garden or pasture. When you’re working outdoors and your presence will deter predators, you can let your birds out of the coop to range. They will naturally return to the coop at dusk to roost, or, if you need to get them inside before dusk, you can easily train them to run into the coop by giving them treats.

For several years, MOTHER EARTH NEWS has been working to develop inexpensive chicken coop plans for folks who want to keep just a few hens or raise a few meat birds. Our goal has been a small, secure, low-cost, DIY, portable chicken coop for use in gardens and backyards. We wanted a coop that would allow the birds to forage on pasture or fertilize garden beds while still keeping them safe from predators. The lightweight, inexpensive, wire-mesh pens we wrote about in the 2007 Portable Chicken Mini-Coop Plan were working well until we discovered a large dog could smash an unreinforced wire unit and kill the hens inside. These ultra-lightweight pens still work great inside a fenced garden or yard where dogs can’t get to them, but for a coop to use in unfenced areas, we’ve developed the improved design shown above, which features a steel frame to support the wire mesh. The coop is still portable, but the frame makes it much more predator-proof. We’re calling it MOTHER’s Mighty Chicken-Mobile, and it’s intended to house three to four hens. Nighttime shelter inside the coop can be a lightweight plastic storage tub, a doghouse or a “room” made from corrugated plastic. (To see an animation of how the coop comes together, view the video at left in the “Related Content” box.

Building MOTHER’s Mighty Chicken-Mobile

To make the steel frame, our DIY guru, Nathan Lindsey, first welded three 2-foot-by-3-foot rectangles from square steel tubing. Next, he welded 10-foot lengths of angle iron to the rectangles, giving us a coop frame 10 feet long, 3 feet wide and 2 feet high. One person can move this 3-by-10-foot unit, and it will fit nicely over most garden beds and in some of the wider paths in your garden. Nathan used 1-inch angle iron, but three-quarter-inch material would make the coop a bit lighter and easier to move.

If you don’t know how to weld, you can take this article to a machine shop and have the frame welded for you, or perhaps now’s the time to learn a new skill (Check out Meld Metals With Welding and Brazing). You could make the frame from wood, but it would not be as strong — and definitely not as durable — as a steel frame. Total cost of materials to build our steel frame was about $100, but you could reduce this by buying the steel from a local salvage yard.

To make the pen easy to move, Nathan added adjustable-height wheels to the back and retractable, 24-inch handlebars to the front. When not in use, the handlebars can be pushed in by sliding them through short tubes welded to the frame’s corners.

Adding a solid roof instead would serve for both shade and keeping the covered area dry during heavy rains (though it may add a little weight, depending what you use). I used a piece of spare corrugated metal roofing on top of a rabbit tractor, which is still in use. I attached the roofing to a piece of board at each end the same lenth as the width of the roofing piece, both to keep the roofing from flopping, and to attach hinges at one end. You lift this "lid" open from the other end, and prop it in place with a plank while servicing the pen. Ours just rests on top of the frame, but you could easily make it more secure by adding a latch or two of some kind.

Chickens need shade, of course. The pictured design offers no protection from the elements for these birds except that little box, which on a sweltering day would be unbearably hot. The well-being of the birds needs to be first and foremost.

Sorry about the link. You need detailed plans and instructions to build functional and good looking chicken coop. Then you also need to know how to raise chicken in proper conditions. You can check this website to learn everything you need to build your own chicken coop.

People don't know how great chickens and chicken coops are! And lots of people don't know how to raise
chicken and build chicken coop. You need <a href="">detailed plans and instructions to build functional and good looking chicken coop.</a> Then you also need to know how to raise chicken in proper conditions.

You are correct, Mary--this coop would not be weasel-proof, especially against the "least weasel" which is only about 7 inches long but will sometimes kill chickens. According to pest control experts, most weasels feed on rodents but sometimes attack chickens. A pen that would protect the birds 24 hours a day from weasels and still allow the birds to feed on pasture is probably impossible. Thanks for the suggestions, John David. Love the bed springs suggestion. Cheryl Long

OK, my posts, because I was limited to 1500 characters, are to be read as one post starting at the bottom. Hope this helps make this chicken tractor better.

If it was raining, I would keep my birds in the coop but they would still be able to scratch without getting soaked. One last thing. Instead of using expensive and heavier square tubing, you can use old box spring metal frames. Whenever I see those left out for trash I pick them up. The steel is remarkably strong so you might need a metal cutting power saw. Sometimes mattress stores throw them out so you can ask them too. Cut to length, butt-weld, then cut a smaller 4 inch section, center it on the butt weld, then weld it in to brace it. Seal it with paint or it *will* rust.

Then you can weld a couple of braces going across and hang your waterer and feeder a couple inches off the ground so the chickens won't kick as much dirt in them. You can open the small door to let the birds in and out or open the large door so you can change their food and water. I also extended the roof with a sheet of ten foot corrugated tin all the way from the back to the front of the coop so they would be shielded from the rain.

I built a tractor like this awhile back but with a few differences. Instead of the complicated adjustable back wheels, just extend the bottom rails about 6 inches further back. When you lift the other end the rails act as levers and the wheels raise the end of the coop plenty above the ground. Also, on the other end where the handles are, instead of just a small door, allow the entire end to hinge open at the top and still keep the smaller door.

While it looks like an awesome chicken tractor, welding is beyond my bag of DIY tricks...

Everytime I put my hens in together, they would peck each other. I had to let them free range, then they were happy, becvause they established pecking order, but could get away from each other and not get pecked all the livelong day. I wish there were a better solution than this, because my neighbors dogs come over and eat my chickens and I'm about to shoot my neighbors dogs...

We have built a similar portable coop, but would like to advise will not keep raccoons from killing your chickens as they can reach through chicken wire, even with offset double layering of the chicken wire. Though coons could not get in or pull chickens through they were able to reach the chickens and do the damage. We lost several, now we have an electric wire around the coop.

I have had weasels kill ducks and a one hen on my place. Weasels are able to get in though quite small openings. I am concerned that the 2" X 4" mesh that you use on the top of this coop will allow weasels to get in.
