Preventing Broken Eggs in your Nesting Boxes:
When chatting up the benefits of keeping chickens, few people mention the battle to keep clean, soft nesting material in a nesting box with hens that are constantly “rearranging” their nest. If you’ve kept chickens for long, chances are you’ve found yourself cleaning raw egg out of a nesting box more than once.
Rearranging their nest is a normal part of chicken nesting behavior, but often hens get carried away and clear a once softly-bedded nesting box to a hard piece of wood protected only by a few sparse pieces of straw. Once the hard bottom of the nest is exposed it’s easy for a hen to accidentally break eggs as she gets in or out of the nest or bickers with other hens over who gets to use their favorite nesting box.
The Solution: A Modern Replacement for Nesting Material
After cleaning up many broken eggs, I decided to experiment with materials to create a soft nest base that would be easy to clean and impossible to move. I wondered if it could work to line the nesting boxes in thick astroturf.
I was curious about experimenting with astroturf as the only nesting material provided, so I purchased a few square feet of thick synthetic turf. The turf I used for my coop is about 1.5″ deep, very dense, and soft to the touch. Buy it by the square foot here. Thin outdoor carpet style turf that putting greens use is easier to find, but I didn’t think it would cushion enough or simulate natural bedding.
When I initially introduced the new synthetic bedding the hens briefly revolted, however placing wooden eggs in the center of each newly bedded nest and blocking off the alternate area they were nesting in during their protest resulted in total success.
When I first penned this article, I’d been using the mats as nest liner for 8 weeks and was immediately pleased with the result. We were able to clean them easily by removing the mats and smacking them against the side of the coop like a rug. This removes the vast majority of debris. The soft mats have completely ended egg-loss that had been caused by eggs bumping boards under scattered straw nesting material. I expect cleaning up tougher messes will involve just a brief soak in a bucket and hosing off (read on to learn more about how I routinely clean mine)

FALL 2020 Update: Great news, turf manufacturers have responded to the popularity of this DIY post and have now added precut 12.5×12.5″ turf nesting box liners on Amazon.

Here’s How I Made my Easy Clean Nesting Boxes:
I hoped the thick pile would feel enough like natural grass that the chickens would adapt to it without needing additional nesting material:
First, I totally cleaned out my nesting boxes. Then I added a few strips of silicone caulking to the bottom of my new mats to add a non-slip grip to help keep the turf mats from slipping. I allowed the caulking to completely dry before adding the turf to the nesting boxes, since I did not want to glue the mats down, only provide traction.
Once the silicone was dry, I added the turf mats:
…And added a few wooden eggs for motivation. Here’s an interior view of my reach-through nesting boxes. My DIY nesting boxes are made from salvaged shipping crates. I just turned the crates on their side, removed the bottom of the crate and then cut a hole in the wall behind them. (For other shipping crate inspired DIYs, check out my Shipping Crate to Planter post)
Initially, my hens wanted to lay on top of the boxes, so the portion above the nesting boxes is filled tightly with crumpled chicken wire salvaged from another project:
Once I blocked off the alternate area above the nesting boxes, success was immediate! Almost immediately my hens began happily laying eggs in their astro-turf lined nesting boxes.
Aside from being easy to clean, I really like that this nesting medium makes it very easy to spot any droppings in the nest. Dirt and droppings tend to blend into a straw nest and often end up transferring to the eggshells. With the astroturf nest I can see right away when I need to pull a mat and shake it off, and my eggs are cleaner than ever.

Update & How to Deep-Clean:
Years in, I still LOVE these liners! My hens have fully adapted to laying eggs on the astro-turf and I even had two chickens happily go broody on the artificial grass-lined nests last summer.
With two broody hens in attack-mode and several weeks of temperatures in the 100’s, I was not good about collecting eggs regularly last August. As a result, my turf nest liners ended up really dirty, with broken shells and rotten egg dried to the mat.
Although a gross cleanup job, it was a good opportunity to put these mats to the test. The Result? I was thrilled with how easily they cleaned up! Cleaning was simple and this method worked well:
1. I pulled mats out of nesting boxes and slapped them against the side of the coop to dislodge loose debris.
2. I then placed mats in a big bucket, filled the bucket with water, and splashed a generous portion of white vinegar on top (about 3 cups to my 10-gallon tub)
3. I left the mats to sit in vinegar-water for about 30 minutes.
4. After 30 minutes, I dumped the now-dirty vinegar water, refilled the bucket with clean water, sloshed mats around, and dumped. I repeated this rinse 3-4 times until water ran clear. The artificial grass was like a sponge to clean, so once the dried-on egg was soaked and soft, they cleaned up easily.
(For faster cleaning, you could also take the mats to a carwash and use the floor mat clips to hold while pressure washing the mats)
5. I think the mats could have gone back in the coop the same afternoon, but I left them on the coop’s roof to dry overnight and placed the artificial grass mats back in the nesting box the next morning.
A few of the comments below have been about the environmental impact of using astroturf nesting box liners vs traditional straw for lining nesting boxes. It’s an important point to consider, but I think at the end of the day it’s probably a wash due to the durability and reusability of the astroturf. Straw, which is quickly scattered and requires replacement, is grown in fields that may require irrigation, harvest by heavy machinery, loading by often underpaid workers, and trucking to agricultural supply stores. A 12″ x 12″ square of Astroturf, although not biodegradable, works for years and years (I’m using the same mats now that I cut in 2013/2014) and because of that likely does not have a greater environmental impact than using straw.
