Here in the sandhills of NC, on our current property, we have sand. It is the nastiest, stinkiest stuff when it gets wet - no matter what is on it (the dogs, the ponies, the chickens). From our understanding, the open pastured areas on our property (about 7 acres total - fenced) was used for growing corn and tobacco years ago. Then had some horses/minis on it before we brought in our ponies. It also turns hard as concrete during the winter - even when dry - and makes it difficult for birds that fly down from even a lower 3' roost. I was not able to "scoop" it every day 1x much less 2x a day. So, we use DLM. The chickens mix it in and then anywhere from 3 - 6 months later we start removing the composted materials for our tire planters and raised bed gardens (just started doing this regularly this year).
I use different materials for my DLM. We just got our first few loads of wood mulch - all new chippings, different trees but mostly pine & pine needles. I have not used it in the chicken pens/coops yet - just in the nests mixed with shredded paper.
DLM is meant to break down and you continue to add to it. Wood chips also break down - that is why it is so good to use in chicken runs and as mulch on gardens. It adds to the soils as it breaks down. DLM is a method to do several things at once - makes a nice, deep bed for your chickens that reduces flies, smells and "moon craters" in the chicken yard; drains/soaks up water from lots of rain when deep enough; creates compost that you can remove and use in your garden with out having to put in a lot of work yourself (the chickens do all the mixing and turning and adding manure)and allows you to dump all your compostable materials in the chicken yard. A lot of wins there!
Mixed in with our coop/pen pics are pics of the DLM we've done - showing different pics of the varieties of materials. Unfortunately, I don't have good pics of the compost I remove - it's still very sandy... though right now. I hope to get it to be more "loamy" in the future - we'll get there. It does drain well.
Coops, Cattle Panels, DLM & Sheds
Our place is very much a learning work in progress as we learn about everything other than ponies/horses. This is the first property we've owned and not rented or leased. In the last few years on this property, we've had a lot of weather changes and we've seen different things happen on it with the changing patterns. It does also affect our coop & run layouts and what we are able to build where.
