One thing I haven't seen discussed is turkeys on deep litter in the coop. I have looked online but haven't found any info on this subject. Also, my turkeys share the coop with our chickens. I know there are great benefits for chickens in the deep litter I use but don't know what effects it has with the turkeys. So far we rob some of the deep litter before it is broken down completely for our compost so I am adding some new shavings every week. The hens and turkeys do a lot of scratching in the litter so there is very little manure on top of the litter. I toss cracked corn around the coop to encourage scratching which helps keep the wood shaving turning over to help with the breakdown. Between the flock and ourselves walking around in the coop it tends to compact the shavings so I use a garden folk to fluff up the litter. It is very interesting that the soil under the litter is not dry (not wet) even tho there has been little rain in the last few weeks and the concrete footings reach more than 2' into the ground. I'm guessing that is a result of the deep litter and is beneficial to the breakdown of the litter and for the healthy bacterial growth in the litter. Oh yeah, both the turkeys and chickens have the run of our backyard everyday. The 7 hens are full grown while the 6 turkeys are about 8 weeks if that makes any difference.
