I have about 15bags of Southern States hardwood stove pellets and I'm out of my horse shaving/pellets.
Right now I've moved my pony out of her reg. stall because it's half flooded and she's now in the middle stall which is a bit higher. It's now has a several inchs of water in the front corner (it's a 10x14) and it's still raining. My mare's stall is still dry with no water so she's okay for now. The water is coming up from underneath so there's not much stopping it.
I'm wondering if it's okay to use the hardwood stove pellets for the pony's stall? That way I can keep her out of the water longer. I would move her into my mare's stall since they are best buds and the stall is 10x18 but my mare is moody because she has been in the stall for so long so I just don't want to chance it.
I can't put them outside at this point as my pasture has trees and it's windy. Besides most of it's a foot underwater also. They are safer inside (cinderblock barn).
I have used stove pellets for bedding without issue - but I did read the packaging very carefully - no additives, and I think the local ones here might actually be pine (if I remember right).
My local Safeway grocery store even carries them in the winter (and best price around) - hoping that they start stocking them soon. And they always seem to have damaged bags for 50% off, I am always snapping those up! (I board - and use the pellets as extra bedding).
I've been using wood stove pellets for bedding for years without issue. The Lignetics factory is nearby and I asked them the difference. They said they use softer woods in the bedding, so it breaks down quicker. Other than that, zero difference...except you can get the wood stove pellets for about $2 less per bag...
I've used the wood stove pellets for years. I've called the manufacture of the brand I buy and they said pine or other soft woods. They never use a hardwood because it also smokes too much when used in a hardwood pellet stove.
I've also been really lucky that none of my horses ever eat them!
If you are using hardwood pellets, there is the risk (probably theoretical if the pellets come from areas where black walnut is not prevalent) of exposure to this known-to-be-toxic substance. And the risk is laminitis, not something mild or trivial. Therefore I don't use them and wouldn't, no matter what a manufacturer told me short of the manufacturer GUARANTEEING there was no black walnut. And good luck with that! Two bucks a bag vs. a life-threatening preventable disease--nope.
But in the OP's case if they were lying around and I could use them in a pinch to keep my horses from standing in water/muck for a couple of days, I'd go for it.
