We were having a constant problem with eggs being broken and eaten, and with very dirty eggs. Cleaning the eggs was taking a significant amount of time, and it was a nasty, smelly job. We needed roll-away nest boxes. There are a number of different designs that can be bought or built. I looked at several different ones before deciding that plastic storage boxes would make an ideal material to start with.
These nest boxes are made from 18 gallon storage boxes that I bought in a 3-pack from Lowes. I used a knife and a saw to cut out the large hole in the front. The only important measurement (other than being sized for your chickens) is that the bottom edge of the hole allows a short piece of 2×4 to be attached to it.
The partition that separates the nest section from the egg section is made of scrap plywood or press board. I just used up some scrap pieces. The edges of the partition have pieces of 2×2 screwed in place to allow for screws to attach it to the sides of the plastic box. The dimensions will vary according to the plastic box used, but my partitions were 14 1/4″ across the top, 12 1/2″ across the bottom, and 11 1/2″ high. The bottom was approximately 2 1/4″ from the top of the fake grass.
The bottom is lined with “fake grass”. This is not the standard indoor/outdoor carpet, but a sturdier material designed to be used as a plastic grass substitute. It was purchased by the foot from Lowes. Although it works well, I found that the hens were much happier with it when I added a very thin layer of hay on top. It was a very thin layer of hay – just enough to make it look like hay rather than plastic. If you put too much hay in, the eggs will not roll out very well.
The nest boxes sit on some boards that form a platform for them. The slope is provided by adding a 2×4, turned on its side under the front.
I will probably end up trimming the fake grass to eliminate places for spiders and other bugs to take up residence. Other than that, I am well satisfied with the design. The eggs are all clean and easy to gather. I either lift the top, or just reach under the partition. Since we started using these nest boxes, we have not had a single broken egg, and all of them are much cleaner than with the old nest boxes.
The finished nest boxes in use. There is a wire that goes from an eye screw below the perch to a screw on the supporting 2x4. Before adding this, the chickens would knock the nest boxes over by standing on the edge.
A piece of 2x4 is screwed to the plastic at the bottom of the opening. This gives the hens something to stand on and provides a place tor the eye screw. The eye screw is used to secure the nest box in place.
Once the approximate gap between the wood partition and the "fake grass" has been established, make sure that the eggs that your hens lay will easily roll to the back. I used a saw to trim off any excess until they easily rolled under the partition.
