Every time I’ve used hay anywhere It is probably the grossest thing I’ve ever dealt with when it gets wet. That’s why I like the straw I use. It doesn’t absorb water like hay and it dries quickly. I just can never get material to dry out which is why I use a thin layer and that is all. I think I personally would stick with straw because it seems like a lot of money to go haul stone and compacted in the run which I’m not even sure other than lots of wheelbarrows How I would get it all back there. I’m not even sure that would work for me considering it is the lowest area of my yard. I never had too much of a issue with it staying wet and told him I tried the deep litter.The straw
works great for me and breaks down for my compost pile. But that’s what I meant before depending on your situation , Size, location and whether really would Really determine what works best for you. Really I think it’s a trial and error process before someone finds what works best for them
Interesting. My experience with hay v straw was the exact opposite! Maybe it depend on the type of grasses used. My hay fluffs back up but the straw stayed matted and wet so the poop couldn't mix in - it just sat on top.
No need for hauling anything- if you want to add anything just do it a bit at a time. Deep litter is a gradual process.
Have you considered a French drain?
