Same here... and I love it that way.
It doesn't cost me anything extra. I don't have to leave my home. And I don't have to think of it as exercise or yard work... I'm simply taking care of my family and pets with the bonus of keeping more fit than not. Yard work by itself is a chore. But doing things for my animals is more like contented mindless movement. And if I get bored or burnt out I just move onto something else.
It's more than just a gym... it's physical therapy and also being outside and doing things that make me feel good benefits my mental health in more ways than I can count!
Truth is with all the mildew, mold and other things here in the PNW... I'm just better off paying a few bucks for hay that was done and stored correctly... My facilities are not conducive to storing things long term... even things that don't get wet grow a top layer of something that smells moldy... even my couch inside my house or the back seat in my car if we don't sit back there often enough! The spores are in the air and they settle... yesterday was 91% humidity. Plus storing hay attracts rats, and I'm already battling them... so one bale my current limit. Also, running a weed eater wrecks my hand joints much faster than a mower.
Saying it was too much work was an easier explanation.

But I think it's great that you are able to use that technique and share it with us! I know another BYC'er (lazy gardener) who stores bags and bags of dry leaves even from neighbors and uses them as her bedding throughout the year.
In my run... what I am aiming for is a forest floor feeling... spongy and soft yet dry and absorbent. Mixture of leaves, pine needles, grass clippings, hay, small branches, or what have you. It's an ongoing renewal process in that area. So far I haven't built up enough stuff to remove and start over. Don't know when that will happen. But for now I am just thankful that when it rains the edges of my run don't stink like they did when I had just the sand that so many recommend... even though it was scooped daily... poo juice stays behind. Bare dirt did nothing for it. But the microbial activity that takes place with deep litter (I call mine semi since I still remove as much dropping as I can see) REALLY made a difference.
