how hot can your area get?
bedding is ideal since it will be easy to clean.. but not more than 1-2 in if you are in the desert state where it can get up to 10+ (or 115-120 here)
since you do not want to have some deep litter/compost pile as the floor the coop/run while in 100+ degree heat
composting is a good way to turn your fruits/veggies waste+ chicken manure/dried leaves,etc.. into compost (without having to pay for them at the store) for your garden
but the thing with compost is it will heat up
when i have new stuffs to add into the bin.. i have to turn it.. and it's like standing next to an oven-- it's a natural process of composting-- heat will be generated in the process as the materials are decomposed by microbes..
deep litter method is pretty much composting..
you do not want to use deep litter method in the desert states-- especially during the hot months.. it's ok during the winter months..
with deep litter bedding and 90+ degree heat.. soon or later your chickens will die of heat stroke
often time they will dig and bury themselves in the ground or stay where it is the coolest..
so having the whole run floor like a hot pan will backfired
my chickens tend to stay on the half side of the run that is bare earth around the pan of water, waterer and wet ground to stay cool..
i don't see them lying on pine shaving side of the run as much anymore .
this is why i left it 50/50
often time it's 110+ here during the summer months
officially, it's still spring but we already getting summer temperatures around here
my city does not have a problem with my coop/run since it's under 300 sq ft in size and under 6ft tall + i keep it out of sight (in the middle of my yard)
originally, i was thinking of only covering half of the roof.. (it's still a learning process for me) after watching them doing their best to stay out of the sun.. i decided to cover the whole roof + the east side of the run as well
i also provide extra shade with these 6'x8 shade screen that i put above the run
i have 3 of these in storage so.. just putting them into good use.
