Sounds like the mulch is too fine if it is creating dust.
I use a mix of things depending on availability:
- Pine horse pellets. I love how they deal with any moisture in the poop and magically turn into sawdust. Not very expensive at TSC.
- Wood chips. I get these for free from local tree companies who are delighted to get rid of them. The chickens love them and freezing has never been an issue.
- Pine shavings. A bit more expensive but still OK. Mostly I use these in the coop and next boxes and the chickens relocate them to the run.
- Shredded paper. Works fine but a pain to shred and not as absorbent as the horse pellets. I feel like it is a good recycle but increasingly I just can’t spare the time.
- Leaves. Free as I live in a clearing in the woods. Chickens go nuts with happiness because they are always full of bugs. Over a few months they really disappear and I think cause dust.
- Chopped straw. I only use this in the coop when it gets really cold as it creates a nice cozy top layer that lasts a good long time. Again the chickens sometimes reorganize and move a lot of it into the run.
As context my run is about 3/4 covered with a real roof and 1/4 open to the sky with a wire roof. In the area that is open to the sky I only use leaves and woodchips. The pellets would become sawdust after the first rain.
