Very similar but less scientific. I ran out of space for the bags of dried leaves - am thinking of putting hooks in the rafters of the Chicken Palace so I can store them up there to dry out for winter use.Yes, this!!! I also bag leaves and pine needles! I use them as a supplement to shavings, as neither are very absorbent. However, as you mention, they LOVE scratching through the leaves (dry ones that are bagged for use through the winter for coop & run) and wet/damp ones in the run for the possibility of creepy crawlies.
Personally, my favorite 'mix' for the coop is: 50% shavings (large flakes) 25% dry leaves & 25% pine needles (approx.) The shavings are absorbent, the leaves give loft & are entertainment for the chooks, and pine needles give a great scent (not toxic). Of course, this only works if you have plenty of free leaves & pine needles to rake up and store.
I also put leaves galore in the run when they are available, but mix in shavings as well (and pine needles) I do deep litter in the run and doing just leaves can result in a matted mess that is much more work to try to keep well mixed for proper microbial action to generate some heat & breakdown.
P.S. I bagged 25 large leaf bags of leaves & pine needles, plus 2 large garbage bins in the fall to use throughout the winter. Unfortunately, I use my last bag of leaves last week. So, no more until late spring![]()
