Anyone using a cultivated deep litter in their coop and runs? I've been using it for some years now but have finally found a combination of materials and a method I really like and it's like a dream to have a coop with no smells, no cleaning out, no flies and that provides the birds with something to do...as well as provide compost for my garden.
I use mostly leaves in the winter months but will occasionally mix in large pine shavings to bulk it up if necessary. This winter I've done all leaves, though some small amounts of hay and straw have found their way into the mix. All spring and summer I deposit garden, flower and herb trimmings in the coop as well. Small twigs, hair and fur, feathers, pine needles and even bones find their way into the coop to mix into the litter.
Good, adjustable ventilation is key and can help keep the chickens warm and dry when it's snowy and damp outside. Another key component is variable particle size and type, such as mixing slow composting materials in with things that break down more quickly and also larger particles that provide air space between finer materials. Large flake shavings, leaves, twigs, pine needles, straw, hay, pine cones, bark, etc. seems to be a great combination, but more leaves than the other materials in the mix, as they break down beautifully.
I just keep the litter lightly flipped under the roosts every other day and then let the chickens do the rest of the rearranging. Lately I've been dumping our scraps in the coop and letting them incorporate what they don't eat right into the litter.
Here's pics of the litter as it changes throughout the seasons and as new materials are added...a lot more are added in the winter months than in the summer...summer usually gets mostly green materials, whereas winter mostly leaves and woodier things that absorb well.
Added benefit of this method of coop maintenance is the healthy, thriving microbial life that can be established and can prevent other, more harmful bacteria and molds taking hold in the coop and run environment. It gives the chickens a more natural habitat in which to live and can help the flock owner work smarter, not harder. So, so much easier to just add to and maintain, rather than shoveling or raking out all the time and trying to deal with bad smells and flies all summer long.
