How to build grazing frames for your backyard chickens

Free plans for backyard chicken frames to grow greens that will last for months.Allowing your chickens to graze on fresh grass is a good thing — not just for them, but for you as well. The nutrients in green vegetation enhances the quality of their eggs and meat. And since fresh greens can make up about 20-30% of a chicken’s diet, providing them for your chickens can save you on feed costs.

But keeping your chickens supplied with fresh greens can be a challenge. When chickens have plenty of room to roam, they will graze a little off the top, then move on. When forage space is limited, however, as in a small urban or suburban backyard, chickens will continue to graze and scratch in the same spot until the vegetation is torn down to the roots.

An easy solution? Grazing frames! But before we get to that, let’s look at some of the more common ways of greening your chickens in a small space.

Some common solutions for feeding fresh greens to your chickens

  • Bring the vegetation to them. Food scraps, garden debris, sprouted grains, and so on are all good ways to get supplemental greens into your chickens’ diet. Just toss them in — or tuck them neatly into a Veggie Feeder — and your chickens will have a feast.
  • Build a chicken tractor. If you have a little more room and are committed to moving the tractor from spot to spot, an open bottom chicken tractor lets you control where the chickens graze in your yard. We rotate our Garden Ark through our vegetable beds so the chickens can till and fertilize the soil and help control weeds and pests. You can also move your chicken tractor across your yard, giving them a fresh spot of grass each time. You’ll want to move it every two or three days to keep them from laying the grass bare.
  • Use a paddock system. This is where you build your chicken coop in the center of three or more enclosed yards, then you give the chickens access to one “sub”-yard at a time. Once they’ve decimated the vegetation in one, you close that yard off for rest and replanting, and let the chickens into the next yard, and so on.
  • Plant vegetation specifically for your hens. This can be part of a paddock, free range, or simple day-run setup. (Here’s a good resource for what to plant.)

All of these are great solutions, depending on your particular space and needs. There’s another solution, though, that I’ve found to be easy to set up and easy to maintain, and that provides a steady source of fresh green grass inside a small space.

Grazing frames for chickens

In our yard, we have one small dedicated day run for our hens located right next to their Garden Coop. In all, it provides only about 100 square feet of grazing area. Fully greened, it would only take a few days for our flock of nine to tear it all down to bare earth. My first attempt at keeping it green was to divide the yard into a couple of paddocks. This required a lot of tending, and there were long stretches of time where both paddocks were closed to recover and regrow.

Then I discovered grazing frames in an article by gardening writer Vern Nelson. Grazing frames are simple two-by-four frames with hardware cloth (welded wire mesh) attached across the top. It’s kind of like a raised bed for chickens. Set one above a patch of grass, and the grass will grow up through the openings. Your chickens can snack on the green tips, and the frame protects the roots so that the grass survives to grow another day.

You can grow and protect grass in your chicken yard for them to graze on for months.

The design I present here is a modified version of Mr. Nelson’s, but it’s basically the same idea: protect the roots, grow the shoots.

A few notes before you start building grazing frames

Assess your skill level. If you’ve used our coop plans to build your backyard chicken coop, you could probably do this project blindfolded (not recommended).

Time. About 30 minutes per frame? Let me know in the comments.

Measurements. Feel free to modify to meet your needs and materials. Metric units appear in green.

Safety. Read our disclaimer. Follow all manufacturers’ instructions when using tools, materials, or equipment. Protect your eyes, ears, and limbs. Build safe, and have fun!

Here’s how to build grazing frames for your backyard chickens

Materials List (to build one 5′ x 3′ frame – 1525 x 865 mm)

  • 2  8-foot (2400 mm) two-by-fours. Note: The wood will be in direct contact with the ground, so either choose a naturally rot-resistant species like cedar or redwood or use a cheaper softwood (spruce, pine, fir) and seal it well or preserve it with a garden-safe product like Timber Pro UV Internal Wood Stabilizer.
  • 1  6-foot (1800 mm) one-by-two. See note above.
  • 3″ (75 mm) exterior screws
  • About 50 galvanized poultry fencing staples (do NOT use ordinary staples from a staple gun!)
  • 59″ (1500 mm) length of 3′ wide (914 mm), 1/2 in. (13 x 13 mm) galvanized hardware cloth, also known as “welded wire mesh”

Tools List

  • Circular saw or handsaw
  • Couple of sawhorses
  • Power driver with assorted drill and driver bits
  • Tape measurer
  • Hammer
  • Wire snips (for cutting hardware cloth)


Cut each of your 2 two-by-fours into a 60″ (1525 mm) piece and a 34″ (865 mm) piece. These will make up the outer edges of the frame (see diagram below).

Cut the one-by-two into two 34″ (865 mm) pieces. These will be the two center spans.

Lightly sand the cut pieces and paint, seal, or treat them as needed with a non-toxic wood preservative like Internal Wood Stabilizer.

Plans for backyard chicken coop grazing frames.

Attach the two-by-four pieces together to form the outer edges of the frame, using 3″ (75 mm) exterior screws, two per joint. Refer to the diagram for placement. You will probably want to pre-drill the holes to prevent splitting.

Attach the one-by-two pieces evenly spaced between the outer edges and flush with what will be the top edge of the frame, using one 3″ (75 mm) screw per joint. By using one-by-twos here instead of two-by-fours, and by attaching them near the top of the frame, they will support the wire mesh without resting on the ground, allowing more grass to grow.

Note: You can build the frame to whatever dimensions you choose, but be sure to space your supports every 2′ or less apart (600 mm). It might seem like overkill, but a flock of hens can be pretty hefty, especially when they all converge in one spot atop the frame.

Protect your grass with a hardware cloth chicken grazing frame.

Attach the hardware cloth to the top of the frame at the perimeter, stapling it down well, every 3-4 inches or so (75-100 mm). There’s no need to attach it to the center supports. If you’ve built a coop using either of our chicken coop plans, you’re already a pro at this!

Prepare an even bed of well-fertilized soil, then plant grass seed or grain. I just fluff up the soil a bit, then scatter the seeds generously and rake them in a bit until they’re mostly buried to about the depth of their diameter. As for what to plant, I’ve used both a mix of grains (wheat, kamut, etc.) and a rye-grass mix with success. The grains gave a faster, more prolific growth, as you can see in the photos below. The rye grass (not pictured) was slower growing and finer, but lasted longer. As of this writing, I think I prefer the grains.

First step is to plant grass or grain seeds in an enclosed patch in your backyard.

Set the frames over the seeded ground, adjust for positioning, and give the whole thing a generous, but gentle watering. Let the sunshine do the rest, and water as needed.

Set the DIY grazing frames over the planted seeds, water, and wait.

Grass or grain seeds will sprout and grow through the top of the hardware cloth for your chickens to graze.

Voila! When the grass tops stick up above the wire, it’s time to let the chickens out into their new pasture paradise. (Actually, you can let them out as soon as you have the frames over the seed. Our hens just happened to be young at the time, so it was them we were waiting on to mature, not the grass.)

Chickens love to graze on pasture, and the nutrients make their eggs and meat more nutritious.

Maintaining your grazing frame grass pasture for chickens

So how do you suppose your hens will repay you for all this work? Like they always do: with poop (then later with eggs). Poop on the grazing frames is a good thing. Simply hose it down through the cracks as you give the bed an occasional watering, and in moderate doses, it will help fertilize the soil.

Too much nitro-poop could burn the plants, though, so keep an eye on it. I usually let the poop dry a bit first, then aim a higher pressure stream of water low and across the surface of the frames, rolling the poop, leaves, and other debris off to the side.

Over time, blades of dead grass may form a thatch atop the mesh. You can lightly rake across the top from time to time to remove this thatch, or simply continue to water.

Eventually, the bed will tire out. The photo below was taken about three months after planting. There is still plenty of life in this patch. I think we got another month or so out of it before we opened it up and let the chickens go to town on the bugs and roots beneath.

Plant and grow nourishing greens for your chickens that will last for months.

When it’s time to replant, the frames have a big advantage over the paddock system in that you can let your chickens back into their day yard right away. The frames protect the seeds from the start.

Pass it on!

Grazing frames are an easy and effective way to supplement your chickens’ diet with fresh grass, yet I’m amazed by how few people are using them. Far from being an advanced chicken keeping technique, this is a simple do-it-yourself project that every backyard chicken keeper should consider. So pass it on!

Of course, continue to give your chickens all the greens and veggie clippings you can find for them, but with a few raised-bed grazing frames in their day yard you can make sure that they have at least some pasture at all times. I believe you’ll notice a difference in both your chickens’ happiness and the quality of their eggs.

I hope you’ve found this tutorial helpful. If you want a do-it-yourself coop to go with your grazing frames, check out our chicken coop plans, available in both U.S. and metric units.

Unlike with the coop plans, I do not offer email support for this free grazing frame plan. But if you have any questions, comments, success stories, or tips on how to keep your backyard chickens in the green, please leave a comment below, and I’ll do my best to respond.
